General annotation (Comments)

Function

May participate in mechanisms of regulated exocytosis in synapses and certain endocrine cell types. May control the properties of the membrane associated cytoskeleton.

Subunit structure

Heterodimer with BIN1. Binds SH3GLB1 and AP2A2 By similarity.

Subcellular location

Cytoplasmic vesiclesecretory vesiclesynaptic vesicle membrane; Peripheral membrane protein; Cytoplasmic side. Cytoplasmcytoskeleton.

Tissue specificity

Neurons, certain endocrine cell types and spermatocytes.

Involvement in disease

Antibodies against AMPH are detected in patients with stiff-man syndrome, a rare disease of the central nervous system characterized by progressive rigidity of the body musculature with superimposed painful spasms.

Sequence similarities

Contains 1 BAR domain.

Contains 1 SH3 domain.
