General annotation (Comments)

Function

Morphologically, spectrin-like proteins appear to be related to spectrin, showing a flexible rod-like structure. They can bind actin but seem to differ in their calmodulin-binding activity. In nonerythroid tissues, spectrins, in association with some other proteins, may play an important role in membrane organization.

Subunit structure

Like erythrocyte spectrin, the spectrin-like proteins are capable of forming dimers which can further associate to tetramers. Interacts with ACP1 By similarity.

Subcellular location

Cytoplasm › cytoskeleton. Cytoplasm › cell cortex.

Domain

Spectrin-like proteins have five domains: (1) N-terminal domain (N), (2) domain between the N-terminal and middle domain (NM), (3) middle domain (M), (4) domain between the middle and C-terminal domain (MC), (5) C-terminal domain (C). NM and MC domains are composed of typical spectrin 106 residues repeats (1-8 for NM and 12-19 for MC) and are homologous to each other. N, M, and C domains are composed of sequences that do not form typical spectrin repeats.

Post-translational modification

Phosphorylation of Tyr-1176 decreases sensitivity to cleavage by calpain in vitro By similarity.

Sequence similarities

Belongs to the spectrin family.

Contains 3 EF-hand domains.

Contains 1 SH3 domain.

Contains 20 spectrin repeats.
