General annotation (Comments)

Function

Isoform neural may associate with CadN and participate in the transmission of developmental information. Can associate with alpha-catenin. Isoform cytoplasmic accumulates through wg signaling; arm function in wg signal transduction is required early in development for determination of neuroblast fate. Arm and Abl proteins function cooperatively at adherens junctions in both the CNS and epidermis. Ref.2

Subunit structure

Interacts with Mer and Moe at the adherens junction. Ref.8

Subcellular location

Cytoplasm. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cell junctionadherens junction By similarity. Note: Inner surface of cell membrane and adherens junction. Ref.8

Tissue specificity

Isoform cytoplasmic is predominant before germ band retraction, after retraction and, during larval stages, it is found in high levels in specific cells along the CNS midline. Isoform neural is first seen after germ band retraction in the axon tracts of the CNS, also present in axons during larval stages and accumulates in the motor neurons of the segmental and intersegmental nerves as they exit the CNS. Both isoforms accumulate in the PNS. Ref.2

Developmental stage

Present at all stages, but reached the highest levels during early to mid-embryogenesis.

Post-translational modification

Phosphorylated on Ser, Thr and Tyr residues. Level of phosphorylation varies both during embryonic development and from embryonic tissue to tissue. Sgg is required for phosphorylation and wg signal negatively regulates arm phosphorylation. Hypophosphorylated form of arm increases in steady-state levels. Ref.7 Ref.9

Sequence similarities

Belongs to the beta-catenin family.

Contains 13 ARM repeats.
