Troponin I is the inhibitory subunit of the troponin complex, a thin filament regulator that confers calcium sensitivity to actomyosin ATPase activity in muscle.
Gene References Into Functions
Troponin I regulates contraction in non-striated actomyosin networks and serves as a crucial cytoskeletal component within the C. elegans reproductive system. PMID: 20388732
It evolved following a gene duplication event originating from the pharyngeal troponin-4 gene. PMID: 15743415
Strongly expressed in body wall muscle during embryogenesis, reduces during the larval stages to adult. In late-stage larvae and adults, expression is evident in the proximal gonad of both hermaphrodites and males.
