NCIt definition : Tropomyosin alpha-1 chain (284 aa, 33 kDa) is encoded by the human TPM1 gene. This
protein plays a role in muscle contraction.;
NCIt note : There are at least 10 isoforms for the tropomyosin alpha-1 chain protein, which result
from alternative splicing. Some of these isoforms are expressed in a cell-type specific
manner. (UniProt);
