[5][6] The protein encoded by this gene is a cytoplasmic actin-binding protein thought to play a role in the process of neuronal growth.

It is a member of the drebrin family of proteins that are developmentally regulated in the brain.

A decrease in the amount of this protein in the brain has been implicated as a possible contributing factor in the pathogenesis of memory disturbance in Alzheimer's disease.

At least two alternative splice variants encoding different protein isoforms have been described for this gene.
