Genes affected

GPR18 (HGNC:4472): (G protein-coupled receptor 18) Predicted to enable G protein-coupled receptor activity. Predicted to be involved in positive regulation of Rho protein signal transduction and positive regulation of cytosolic calcium ion concentration involved in phospholipase C-activating G protein-coupled signaling pathway. Predicted to act upstream of or within T cell differentiation; negative regulation of leukocyte chemotaxis; and negative regulation of tumor necrosis factor production. Predicted to be located in plasma membrane. Predicted to be integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

GPR18 links:

UBAC2 (HGNC:20486): (UBA domain containing 2) Involved in negative regulation of canonical Wnt signaling pathway and negative regulation of retrograde protein transport, ER to cytosol. Acts upstream of or within protein localization to endoplasmic reticulum. Located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]
