nanos homolog 2 [Homo sapiens]

Protein Classification

nanos family protein( domain architecture ID 10530272)

nanos family protein contains a zinc finger domain (called nanos RNA binding domain), similar to Drosophila melanogaster protein nanos, a maternal RNA-binding protein that is required for germ cells proliferation and self-renewal

Nanos RNA binding domain; This family consists of several conserved novel zinc finger domains found in the eukaryotic proteins Nanos and Xcat-2. In Drosophila melanogaster, Nanos functions as a localized determinant of posterior pattern. Nanos RNA is localized to the posterior pole of the maturing egg cell and encodes a protein that emanates from this localized source. Nanos acts as a translational repressor and thereby establishes a gradient of the morphogen Hunchback. Xcat-2 is found in the vegetal cortical region and is inherited by the vegetal blasomeres during development, and is degraded very early in development. The localized and maternally restricted expression of Xcat-2 RNA suggests a role for its protein in setting up regional differences in gene expression that occur early in development.
