General annotation (Comments)

Function

May act as a mediator of the PTEN growth-suppressive signaling pathway. May play a role in developmental processes.

Subcellular location

Cytoplasm.

Tissue specificity

Ubiquitously expressed in all fetal tissues examined including heart, brain, liver, and kidney. Also expressed at lower levels in both adult heart and hypertrophic heart.

Sequence similarities

Contains 2 ANK repeats.

Contains 2 BTB (POZ) domains.

Sequence caution

The sequence AAQ04661.1 differs from that shown. Reason: Frameshift at positions 202 and 212.
