Protein

Protein 4.1

Gene

Epb41

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

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 (By similarity).By similarity

Post-translational modificationi

O-glycosylated; contains N-acetylglucosamine side chains in the C-terminal domain.By similarity
Phosphorylated at multiple sites by different protein kinases and each phosphorylation event selectively modulates the protein's functions.
Phosphorylation on Tyr-654 reduces the ability of 4.1 to promote the assembly of the spectrin/actin/4.1 ternary complex.
