The PIK3R2 antibody is a crucial tool for studying the phosphoinositide 3-kinase (PI3K) signaling pathway, which regulates cell growth, survival, and metabolism. PIK3R2 (Phosphoinositide-3-Kinase Regulatory Subunit 2) encodes the p85β regulatory subunit of class IA PI3K. This subunit binds to the p110 catalytic subunit, modulating PI3K activity and downstream effectors like AKT and mTOR. Dysregulation of PIK3R2 is implicated in cancer, insulin resistance, and neurological disorders.
PIK3R2-specific antibodies are widely used in Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF) to detect protein expression, localization, and post-translational modifications in tissues or cell lines. Researchers employ these antibodies to investigate PI3K pathway activation in diseases, particularly cancers with PI3K/AKT/mTOR pathway mutations. Notably, germline PIK3R2 mutations are linked to megalencephaly-polymicrogyria-polydactyly-hydrocephalus (MPPH) syndrome, making the antibody valuable for neurodevelopmental disorder studies.
Commercial PIK3R2 antibodies are typically raised in rabbits or mice against specific epitopes (e.g., human PIK3R2 N-terminal or SH2 domains). Validation includes knockout cell controls to confirm specificity. Recent studies also explore PIK3R2's role in immune regulation and its potential as a therapeutic target. Proper antibody selection remains critical due to isoform diversity (p85β, p55β, p50β) and homology with other regulatory subunits like PIK3R1.
