About PIK3R3

Cytogenetic location: 1p34.1 Genomic coordinates (GRCh38): 1:46,040,140-46,174,901 (from NCBI)

This gene has 7 transcripts (splice variants), 277 orthologues and 2 paralogues. Broad expression in testis (RPKM 19.6), fat (RPKM 8.4) and 20 other tissues.

Summary

Phosphatidylinositol 3-kinase (PI3K) phosphorylates phosphatidylinositol and similar compounds, which then serve as second messengers in growth signaling pathways. PI3K is composed of a catalytic and a regulatory subunit. The protein encoded by this gene represents a regulatory subunit of PI3K. The encoded protein contains two SH2 domains through which it binds activated Protein Tyrosine Kinases to regulate their activity. [provided by RefSeq, Jun 2016]
