TissueNA
Tissue SpecificityExpressed in ciliary body epithelia, sclera, cornea, and retinal pigment epithelium (at protein level) (PubMed:12710941). Expressed in lung and endometrial tissue;
expression is particularly abundant in secretory endometrium (at protein level) (PubMed:12710941). Expressed in placental villous syncytiotrophoblasts and cytotrophoblasts and on the membrane of interstitial trophoblasts (at protein level) (PubMed:28295343). {ECO:0000269|PubMed:12710941, ECO:0000269|PubMed:28295343}.
