Parkinson's Disease (PD)

There were 103 proteins identified with some association with Parkinson's disease, one of which (AAKG2_HUMAN) was discarded for being a false positive, leaving 102 proteins that will be looked at here. This work has been done with databases that were downloaded from the EBI around the end of 2018 and start of 2019.

Unlike the previous occasion, I decided to keep Beta-synuclein (SYUB_HUMAN) in the dataset because of its connection with Alzheimer's disease which I think might be of greater interest, even though strictly speaking this protein can be seen as a false positive.

The basic imagery will be displayed here but the more in-depth analysis will be written for the second instalment/chapter for the book that I am writing (see below) and this will hopefully be released some time in the latter parts of 2019....hopefully, all being well.

Alzheimer's disease

There are a total of 98 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 at the end of 2018 and the start of 2019.

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 e-publishing sites like Kindle and I will probably do this in parts to make its publication easier for myself.

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. You will find some of the Perl scripts code on the additional resources page and these are 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, 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.

Additional Resources for the Book

There are some additional resources that will be available located on the Additional Resources page.

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).
