TissueNA
Tissue SpecificityExpressed at higher levels in heart, lung, ovary, spleen, intestine and placenta, and at lower levels in liver, colon, pancreas, kidney, thymus, skeletal muscle and prostate. Expressed in tumors such as melanoma, breast cancer, ovarian cancer and glioblastoma. A shorter form probably lacking the signal sequence is found in testis and in EB1 cells undergoing p53/TP53-dependent apoptosis. {ECO:0000269|PubMed:10441517, ECO:0000269|PubMed:11103812, ECO:0000269|PubMed:18929642, ECO:0000269|PubMed:19590037}.
