General annotation (Comments)

Function

Plays a role as a regulator of Rho activity during cytokinesis. May play a role in junctional plaques. Ref.6

Subunit structure

Interacts with PDZD2 By similarity. Interacts (via the C-terminus) with FRMPD2 (via the PDZ 2 domain). Interacts with RHOA; the interaction is detected at the midbody. Interacts with ECT2; the interaction is detected at the midbody. Ref.6 Ref.11

Subcellular location

Cell junctiondesmosome. Cytoplasmcytoskeletonspindle. Cytoplasmcytoskeletonspindle pole. Midbody. Cell membrane; Peripheral membrane protein. Note: Associated with the pericentrosomal region in interphase and with spindle poles during mitosis. In anaphase, during chromosome segregation, is recruited to the central microtubule bundle, focussed at the spindle midzone and ultimately localizes to the midbody at cytokinesis. Constituent of the midbody cytoskeletal matrix. Colocalized with desmoplakin at desmosomal junctional plaques in cultured epithelial cells. Ref.6

Sequence similarities

Belongs to the beta-catenin family.

Contains 9 ARM repeats.

Sequence caution

The sequence CAA57478.1 differs from that shown. Reason: Erroneous termination at position 1193. Translated as stop.

The sequence CAA57478.1 differs from that shown. Reason: Frameshift at positions 334, 337, 864 and 874.

Ontologies

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
