About PPFIA1

Cytogenetic location: 11q13.3 Genomic coordinates (GRCh38): 11:70,270,690-70,384,396 (from NCBI)

This gene has 27 transcripts (splice variants), 1 gene allele, 203 orthologues and 5 paralogues. Ubiquitous expression in testis (RPKM 18.0), thyroid (RPKM 12.7) and 25 other tissues.

Summary

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. This protein binds to the intracellular membrane-distal Phosphatase domain of tyrosine Phosphatase LAR, and appears to localize LAR to cell focal adhesions. This interaction may regulate the disassembly of focal adhesion and thus help orchestrate cell-matrix interactions. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]
