General annotation (Comments)

Function

Binds to poly-G sequences in RNA. May function in post-translational regulation processes. Ref.4

Subcellular location

Cytoplasm Ref.2 Ref.3 Ref.4.

Tissue specificity

Expressed in oocytes, and in specialized cell types such as neural retina cones in adults. Ref.2 Ref.3

Developmental stage

Expressed both maternally and zygotically throughout oogenesis and embryogenesis through to at least the tadpole stage. Also expressed in adults. Ref.1 Ref.3

Post-translational modification

Phosphorylated. Phosphorylation enhances RNA binding. Ref.4

Sequence similarities

Belongs to the krueppel C2H2-type zinc-finger protein family.

Contains 37 C2H2-type zinc fingers.

Contains 1 KRAB domain.
