Protein: Immunoglobulin-like domain-containing receptor 2 (Angulin-3) (Q71H61)
Organism: Homo sapiens (Human)
Function: May be involved in ER stress pathways with effects on lipid homeostasis and insulin secretion. With ILDR1 and LSR, involved in the maintain of the epithelial barrier function through the recruitment of MARVELD2/tricellulin to tricellular tight junctions (By similarity). Also functions as a B7-like protein family member expressed on immune cells and inflamed tissue and with T-cell inhibitory activity. In the inner ear, may regulate alternative pre-mRNA splicing via binding to TRA2A, TRA2B and SRSF1 (By similarity).
