Functioni

Protein 4.1 is a major structural element of the erythrocyte membrane skeleton. It plays a key role in regulating membrane physical properties of mechanical stability and deformability by stabilizing spectrin-actin interaction. Recruits DLG1 to membranes. Required for dynein-dynactin complex and NUMA1 recruitment at the mitotic cell cortex during anaphase.By similarity

Post-translational modificationi

Phosphorylated at multiple sites by different protein kinases and each phosphorylation event selectively modulates the protein's functions.By similarity
Phosphorylation on Tyr-413 reduces the ability of 4.1 to promote the assembly of the spectrin/actin/4.1 ternary complex.By similarity

Interactioni

Subunit structurei

Binds with a high affinity to glycophorin and with lower affinity to band III protein. Associates with the nuclear mitotic apparatus. Binds calmodulin, CENPJ and DLG1. Also found to associate with contractile apparatus and tight junctions. Interacts with NUMA1; this interaction is negatively regulated by CDK1 during metaphase and promotes anaphase-specific localization of NUMA1 in symmetrically dividing cells.By similarity
