Summaries for PPFIA2 Gene

Entrez Gene Summary for PPFIA2 Gene

  • The protein encoded by this gene is a member of the LAR protein-tyrosine phosphatase-interacting protein (liprin) family. Liprins interact with members of LAR family of transmembrane protein tyrosine phosphatases, which are known to be important for axon guidance and mammary gland development. It has been proposed that liprins are multivalent proteins that form complex structures and act as scaffolds for the recruitment and anchoring of LAR family of tyrosine phosphatases. This protein has been shown to bind the calcium/calmodulin-dependent serine protein kinase (MAGUK family) protein (also known as CASK) and proposed to regulate higher-order brain functions in mammals. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

GeneCards Summary for PPFIA2 Gene

PPFIA2 (PTPRF Interacting Protein Alpha 2) is a Protein Coding gene. Among its related pathways are Transmission across Chemical Synapses and Neurotransmitter Release Cycle. GO annotations related to this gene include nucleotide binding and protein complex binding. An important paralog of this gene is PPFIA1.

UniProtKB/Swiss-Prot for PPFIA2 Gene

  • Alters PTPRF cellular localization and induces PTPRF clustering. May regulate the disassembly of focal adhesions. May localize receptor-like tyrosine phosphatases type 2A at specific sites on the plasma membrane, possibly regulating their interaction with the extracellular environment and their association with substrates.
