PIK3R1 - Wikipedia
Phosphatidylinositol 3-kinase regulatory subunit alpha is an enzyme that in humans is encoded by the PIK3R1 gene. [5] Function. Phosphatidylinositol 3-kinase phosphorylates the inositol ring of phosphatidylinositol at the 3-prime position. The enzyme comprises a 110 kD catalytic subunit and a regulatory subunit of either 85, 55, or 50 kD.

PIK3R1 (phosphoinositide-3-kinase regulatory subunit 1) belongs to class IA of the PI3K family. PIK3R1 exhibits structural complexity due to alternative splicing, giving rise to distinct isoforms, prominently p85α and p55α.
The Role of PIK3R1 in Metabolic Function and Insulin Sensitivity
2023年8月11日 · PIK3R1 (also known as p85α) is a regulatory subunit of phosphoinositide 3-kinases (PI3Ks). PI3K, a heterodimer of a regulatory subunit and a catalytic subunit, phosphorylates phosphatidylinositol into secondary signaling molecules involved in regulating metabolic homeostasis.

2022年4月8日 · Phosphoinositide-3-Kinase Regulatory Subunit 1 (PIK3R1) is believed to function as a tumor suppressor, while Phosphoinositide-3-Kinase Regulatory Subunit 2 (PIK3R2) as a tumor driver.
PHOSPHATIDYLINOSITOL 3-KINASE, REGULATORY SUBUNIT 1; PIK3R1 …
The PIK3R1 gene encodes 3 regulatory isoforms of PI3K: p85, p55, and p50. The 9 3-prime exons are shared by all 3 isoforms with 2 distinct promoters, and 2 exon 1 sequences upstream of these 9 exons control the production of p55 and p50 (summary by Conley et al., 2012).
