Background
| Function | FUNCTION: Plays a role in ciliogenesis. {ECO:0000269|PubMed:26167768}.; FUNCTION: [Isoform 1]: Pericentriolar protein required to maintain mitotic spindle pole integrity (PubMed:21224392). Required for the centrosomal accumulation of PCM1 and the recruitment of centriolar satellite proteins such as BBS4. Via association with PCM1 may be involved in primary cilia formation (PubMed:23110211). Required for CEP63 centrosomal localization and its interaction with WDR62. Together with CEP63 promotes centriole duplication. Promotes the centrosomal localization of CDK2 (PubMed:26297806). {ECO:0000269|PubMed:21224392, ECO:0000269|PubMed:23110211, ECO:0000269|PubMed:26297806}.; FUNCTION: [Isoform 4]: The secreted form is a mediator of progesterone that by acting on the phospholipase A2 enzyme interferes with arachidonic acid metabolism, induces a Th2 biased immune response, and by controlling decidual naturakl killer cells (NK) activity exerts an anti-abortive effect (PubMed:14634107, PubMed:3863495, PubMed:12516630). Increases the production of Th2-type cytokines by signaling via the JAK/STAT pathway. Activates STAT6 and inhibits STAT4 phosphorylation. Signaling via a not identified receptor seems to implicate IL4R and a GPI-anchored protein (PubMed:16393965, PubMed:25218441). {ECO:0000269|PubMed:12516630, ECO:0000269|PubMed:14634107, ECO:0000269|PubMed:16393965, ECO:0000269|PubMed:25218441, ECO:0000269|PubMed:3863495, ECO:0000305|PubMed:11407300}. |

| Tissue Specificity | Expressed at highest levels in testis. Moderate expression is detected in spleen, thymus, prostate, ovary, small intestine, and colon (PubMed:11935316). Expressed in the first trimester pregnancy decidua (PubMed:12516630). Localized to extravillous cytotrophoblast (at protein level). Also found in syncytiotrophoblast and part of the villous cytotrophoblast. Isoform 1 is expressed in first trimester and term villous trophoblast; trophoblast cells can additionally express other isoforms (PubMed:18817979). Overexpressed in solid tumors from stomach and uterus and in cells from ovary, cervical, breast, lymphoma and leukemia cancer (PubMed:25218441). {ECO:0000269|PubMed:11935316, ECO:0000269|PubMed:12516630, ECO:0000269|PubMed:18817979, ECO:0000305|PubMed:25218441}. |
