Parkinson's Disease (PD)

The script picked up 95 proteins with some association with Parkinson's disease, two of which were discarded for being false positives so leaving 93 proteins that are looked here. This work has been done with a database that was downloaded from the EBI on the 7th & 8th of January 2017.

Disease Motifs - A Wild Speculative Excursion into the Field of Bioinformatics

I am in the process of writing a book about this work in general with all the explanations necessary and with the results of some of the research that has been conducted. Hopefully this might help and inspire other individuals to become involved. The book will be self-published on Lulu and other epublishing sites like Kindle and I will probably do this in parts to make its publication easier for myself.


The Introduction can now be found on Lulu and is free to download. Just click on the link to download. The Introduction to the book is free but subsequent chapters will be sold.

Disease Motifs. A Wild Speculative Excursion into the Field of Bioinformatics: - The Basics

The first chapter or book one is called the Basics and is now available on Kindle, Amazon. It will instruct you into the basics of the work that is displayed on this site. I have included the Introduction (as described above which, by itself, is still free to download) in this work just to keep everything together. You will find some of the Perl scripts code on the additional resources page, while this site still exists as I am about to abandon it, but it is also included in the appendices of The Basics. I hope that you will not find this work too labourious. I am currently working on the Parkinson's dataset and will release this some time next year, hopefully.

Please be aware that this instalment has a lot of colour images and that you will be restricted on having this to one device, so you might well think to download it on to your computer, if your Kindle or other device does not show coloured images properly.

The Parkinson's Disease Protein Dataset 2019

The second chapter, or instalment, will be called "The Parkinson's Disease Protein Dataset 2019"; which will hopefully be ready for release sometime in the year 2019, if everything goes okay. This will explore some of the proteomics involved in the pathology and also investigate the possibility that there may be some microbial candidates for a pathogenic cause of Parkinson's disease.

Preliminary set theory-type analysis of proteins associated with Parkinson's disease
- published paper 2014


In an attempt to create a model of Parkinson's disease (PD) eighty-three proteins were extracted from the Swiss-Prot protein database that had some casual mention of PD. These were split up into various subsets of proteins of which three are focused on here: PARK, made up of proteins that had some indication that polymorphisms in the protein might increase a person's susceptibility to develop PD; MITOCHOND, proteins which had some association with the mitochondria; and MT-C1D, proteins that were implicated in mitochondrial complex 1 deficiency. The PARK subset had 21 out of 83 proteins (21/83); MITOCHOND 33 out of 83 proteins (33/83); and MT-C1D 17 out of 83 proteins (17/83). The results could be used to build up a basic model of PD creating phenotypes based on sets of proteins. The main phenotypes established here are; non-mitochondrial PD (50/83) and mitochondrial PD (33/83). Further division is possible dependant on whether proteins have polymorphisms which increase susceptibility to develop PD. MT-C1D seems to be independent of the PARK set. This is a very simplistic attempt at trying to model Parkinson's disease at the proteomic level and will need further work to build up the more complex and realistic PD proteomic disease model.

Theoretical Biological Switch With a Possible Important Role In Parkinson's Disease, Schizophrenia, Hyposmia and the Onco-Parkinson's Mechanism


Antagonists for the Histamine Receptor H2 (HRH2_HUMAN) protein may have some efficacy in reducing levodopa-induced dyskinesia in Parkinson's disease. Using short sequence proteomic analysis on the histamine receptor 2 which involves splitting this protein sequence into smaller fragments of ten amino acids and contrasting (using BLAST) against the human protein database.

Three main motifs were found; with the initial two being named the CW-motif and the NxxxNP-motif, with the adjacent amino acid residues being important. The third motif NPxxY overlays the end of the NxxxNP-motif and may form part of a rhodopsin NPxxY(x)5,6F type motif but in this case, it is a variant form NPxxY(x)6,7F present in many of the serotonin and dopamine receptors found here. Using the variants of NPxxY found in the dopamine and serotonin receptors, as a specific amino acid search-term (non-BLAST), it was found that a high proportion of the proteins returned were olfactory proteins.

This small region of similarity amongst dopamine, serotonin and olfactory receptors might be suggestive of a biological switch which might play an important role in Parkinson's disease, schizophrenia and the onco-Parkinson's effect seen in people with Parkinson's disease (who may have raised or lower risk of developing certain types of cancer).

Alzheimic Parkinson's Disease

Consisting of 11 proteins that have some mention of Alzheimer's Disease and PD. One of these has no polyphorphisms connected with the increased chance of developing a particular disease.

Alzheimer's disease

There are a total of 96 proteins that seem to have some mention of Alzheimer's disease within the comments section of the protein datasheet. None were excluded. This work was done using a database that was downloaded from the EBI on the 7th & 8th of January 2017.

Proteomic Analysis of the Amyloid Precursor A4 Protein Proteomic Analysis of the Amyloid Precursor A4 Protein

Not published in scientific journal but this paper is available as an e-paper. This is just a five page article or paper but will help fund my work.


This work demonstrates the principle of using sequence similarity to link possible causative microbial pathogens to particular parts of proteins that are associated with a particular disease. A small 10 amino acid sequence of amyloid precursor protein, including residues 711 and 713, were matched against the viral Swiss-Prot protein database for sequences of close similarity. This was conducted in the amino-carboxyl direction (NC) but also in the reversed direction (CN) i.e. the sequence was reversed. In the reversed (CN) direction two small three amino-acid (Valine-Isoleucine-Alanine and Valine-Glycine-Glycine) motifs were found in the capsid protein from the Venezuelan equine encephalitis virus (VEEV) and Eastern equine encephalitis virus (EEEV). This possibly suggests that there might be some link between these viral proteins and the amyloid precursor protein which may be more apparent in people who become infected with either of these two viruses e.g. People who die from infection of the virus may have an increased level of beta amyloid 40 or 42.
