DAB2IP
DAB2IP (AIP1, AF9Q34) is a human chromosome 9q33.2 gene encoding a Ras GTPase-activating protein tumor suppressor that inhibits Ras, NF-κB, PI3K/AKT, and other oncogenic pathways; it is frequently silenced by methylation in prostate, breast, colorectal, and lung cancers.
GNAQ
GNAQ (G protein subunit alpha q), human gene at 9q21.2 encoding the Gq alpha subunit coupling GPCRs to phospholipase C-beta. Somatic R183Q mutations cause Sturge-Weber syndrome; Q209/R183 hotspot mutations drive uveal melanoma.
LRP6
LRP6 (low-density lipoprotein receptor-related protein 6) is a Wnt co-receptor essential for canonical Wnt/β-catenin signaling, more potent than its paralog LRP5, with roles in development, bone, and Hippo signaling.
PIK3CB
PIK3CB (p110beta) is a human gene at 3q22.3 encoding the beta catalytic subunit of class IA phosphoinositide 3-kinase, a ubiquitous lipid kinase activated by both RTKs and GPCRs, central to PTEN-deficient tumors and thrombosis, and targeted by inhibitors such as TGX-221 and AZD8186.
PIK3R1
PIK3R1 (p85alpha, GRB1, IMD36) is a gene at 5q13.1 encoding the p85α regulatory subunit of PI3K; germline mutations cause APDS2 immunodeficiency and SHORT syndrome, somatic mutations drive endometrial and other cancers.
RHEB
RHEB (Ras homolog enriched in brain) is a small GTPase of the Ras superfamily and the direct activator of mTORC1, which controls cell growth and metabolism.
