Cancer Protein Description

This report provides a detailed description of a selected cancer protein with information collected from various sources, including UniProt, the Wellcome Trust Sanger Institute’s Catalogue of Somatic Mutations in Cancer (COSMIC), and the Atlas of Genetics and Cytogenetics in Oncology and Haematology.


Protein Name: PIK3R2
Gene Name: PIK3R2
Protein Full Name: Phosphatidylinositol 3-kinase regulatory subunit b
Alias: P85; P85B; Phosphoinositide-3-kinase, regulatory subunit 2 (beta); PI3K p85-beta; PI3-kinase p85-beta; PtdIns-3-kinase p85-beta
Mass (Da): 81624
Number AA: 728
UniProt ID: O00459
Locus ID: 5296
COSMIC ID: PIK3R2
Gene location on chromosome: 19q13.2-q13.4
