Entrez ID 6453
Gene name Intersectin 1
Gene symbol ITSN1
Synonyms (NCBI Gene)
ITSNSH3D1ASH3P17
Chromosome 21
Chromosome location 21q22.11
Summary The protein encoded by this gene is a cytoplasmic membrane-associated protein that indirectly coordinates endocytic membrane traffic with the actin assembly machinery. In addition, the encoded protein may regulate the formation of clathrin-coated vesicles
