Expressioni

Tissue specificityi

Expressed both maternally and zygotically. Expressed uniformly in large quantities in the early embryo (stages 1-4). In the late embryo, expression is ubiquitous, but expression levels are dramatically reduced. Expressed in the adult head and thorax, and in S2 cells.1 Publication
