The function of Ensembl gene identifier ENSG00000196091 (MYBPC1, myosin binding protein C1) is as follows. Thick filament-associated protein located in the crossbridge region of vertebrate striated muscle a bands. Slow skeletal protein that binds to both myosin and actin (PubMed:31025394, PubMed:31264822). In vitro, binds to native thin filaments and modifies the activity of actin-activated myosin ATPase. May modulate muscle contraction or may play a more structural role. {ECO:0000269|PubMed:31025394, ECO:0000269|PubMed:31264822}.
