CC -!- FUNCTION: May play an important role in trophoblast development and in
CC the regulation of bone formation.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in placenta, uterus and in fetal
CC perichondrium. Expression levels were increased in both early placentas
CC and molar pregnancies and were reduced in choriocarcinoma cells.
CC {ECO:0000269|PubMed:12414911, ECO:0000269|PubMed:9740319}.
CC -!- DEVELOPMENTAL STAGE: Highly expressed in the early placenta. Expression
CC of epil peptides in the villous cytotrophoblast is different from that
CC displayed by the syncytiotrophoblast. In fetal tissues it was
CC identified in the perichondrium of all four limbs, vertebrae, and ribs.
CC It was abundant in interbone ligaments.
CC -!- SIMILARITY: Belongs to the insulin family. {ECO:0000305}.
