Protein attributes

Sequence length	180 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Subcellular location	Cytoplasm Ref.10.
Tissue specificity	Expressed in testis and ovary and in a wide variety of cancers. Detected in uterine myometrium. Expressed from 18 weeks until birth in human fetal testis. In the adult testis, is strongly expressed in spermatogonia and in primary spermatocytes, but not in post-meiotic cells or in testicular somatic cells (at protein level). Ref.10
Sequence similarities	Belongs to the CTAG family.
