NECAP1

Chr 12AR

NECAP endocytosis associated 1

The encoded protein localizes to clathrin-coated vesicles and binds adapter protein complexes to facilitate endocytosis. Loss-of-function mutations cause developmental and epileptic encephalopathy 21, inherited in an autosomal recessive pattern. The pathogenic mechanism involves disrupted endocytosis due to impaired clathrin-coated vesicle function.
