Summaries for PIK3R3 Gene

Entrez Gene Summary for PIK3R3 Gene

  • 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]

GeneCards Summary for PIK3R3 Gene

PIK3R3 (Phosphoinositide-3-Kinase Regulatory Subunit 3) is a Protein Coding gene. Diseases associated with PIK3R3 include Intravenous Leiomyomatosis. Among its related pathways are PI-3K cascade-FGFR3 and ICos-ICosL Pathway in T-Helper Cell. GO annotations related to this gene include 1-phosphatidylinositol-3-kinase activity and 1-phosphatidylinositol-3-kinase regulator activity. An important paralog of this gene is ENSG00000278139.

UniProtKB/Swiss-Prot for PIK3R3 Gene

  • Binds to activated (phosphorylated) protein-tyrosine kinases through its SH2 domain and regulates their kinase activity. During insulin stimulation, it also binds to IRS-1.

Tocris Summary for PIK3R3 Gene

  • PI 3-Kinases (phosphoinositide 3-kinases, PI 3-Ks) are a family of lipid kinases capable of phosphorylating the 3'OH of the inositol ring of phosphoinositides. They are responsible for coordinating a diverse range of cell functions including proliferation and survival.
