Gene: SMTN (smoothelin) Homo sapiens
Symbol: SMTN
Name: smoothelin
Description: This gene encodes a structural protein that is found exclusively in contractile smooth muscle cells. It associates with stress fibers and constitutes part of the cytoskeleton. This gene is localized to chromosome 22q12.3, distal to the TUPLE1 locus and outside the DiGeorge syndrome deletion. Alternative splicing of this gene results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, May 2011]
Type: protein-coding
RefSeq Status: REVIEWED
