Tissue Specificity[Isoform 2]: The predominant isoform in human tissues. Expressed in adipose tissue, pancreatic islets, lung and brain. Expressed in alpha cells of pancreatic islets (PubMed:24742677). Expressed in primary cilia of perivascular preadipocytes of white adipose tissue (at protein level) (PubMed:31761534). {ECO:0000269|PubMed:24742677, ECO:0000269|PubMed:31761534}.;
Abundant expression in the intestinal tract. Expressed in colonic intraepithelial neuroendocrine cells. {ECO:0000269|PubMed:15619630}.

Multi-pass membrane protein {ECO:0000255}. Note=Sorted to late endosome/lysosome compartments upon internalization (PubMed:22282525). Specifically localizes to the primary cilium of undifferentiated adipocytes. Ciliary trafficking is TULP3-dependent. As the cilium is lost during adipogenesis, moves to the plasma membrane (Probable). {ECO:0000269|PubMed:22282525, ECO:0000305|PubMed:31761534}.
