Everything about Protein Tyrosine Phosphatase totally explained

Protein tyrosine phosphatases (PTPs) are a group of enzymes that remove phosphate groups from phosphorylated tyrosine residues on proteins.

Functions

Together with tyrosine kinases, PTPs regulate the phosphorylation state of many important signalling molecules, such as the MAP kinase family.
   PTPs are increasingly viewed as integral components of signal transduction cascades, despite little studied and ill-understood compared to Tyrosine Kinases.
   PTPs have been implicated in regulation of many cellular processes, including, but not limited to:

Genes

  • receptor type: PTPRA, PTPRB, PTPRC, PTPRD, PTPRE, PTPRF, PTPRG, PTPRH, PTPRJ, PTPRK, PTPRM, PTPRN, PTPRN2, PTPRO, PTPRQ, PTPRR, PTPRS, PTPRT, PTPRU, PTPRZ1, PTPRZ2
  • non-receptor type: PTPN1, PTPN2, PTPN3, PTPN4, PTPN5, PTPN6, PTPN7, PTPN9, PTPN11, PTPN12, PTPN13, PTPN14, PTPN18, PTPN20A, PTPN20B, PTPN20C, PTPN21, PTPN22, PTPN23

    External Link Exchanges

    Do you know how hard it is to get a link from a large encyclopaedia? Well we're different and will prove it. To get a link from us just add the following HTML to your site on a relevant page:

      <a href="http://protein_tyrosine_phosphatase.totallyexplained.com">Protein tyrosine phosphatase Totally Explained</a>

    Then simply click through this link from your web page. Our crawlers will verify your link, extract the title of your web page and instantly add a link back to it. If you like you can remove the words Totally Explained and embed the link in article text.
       As long as your link remains in place, we'll keep our link to you right here. Please play fair - our crawlers are watching. Your site must be closely related to this one's topic. Any kind of spamming, dubious practises or removing the link will result in your link from us being dropped and, potentially, your whole site being banned.
