About PIK3R2

Cytogenetic location: 19p13.11 Genomic coordinates (GRCh38): 19:18,153,163-18,170,532 (from NCBI)

This gene has 11 transcripts (splice variants), 248 orthologues, 2 paralogues and is associated with 3 phenotypes. Ubiquitous expression in brain (RPKM 16.0), skin (RPKM 12.1) and 25 other tissues.

Summary

Phosphatidylinositol 3-kinase (PI3K) is a lipid kinase that phosphorylates phosphatidylinositol and similar compounds, creating second messengers important in growth signaling pathways. PI3K functions as a heterodimer of a regulatory and a catalytic subunit. The protein encoded by this gene is a regulatory component of PI3K. Three transcript variants, one protein coding and the other two non-protein coding, have been found for this gene. [provided by RefSeq, Apr 2019]
