Gene: TNNI2 (troponin I2, fast skeletal type) Homo sapiens
Symbol: TNNI2
Name: troponin I2, fast skeletal type
Description: Exhibits troponin T binding activity. Contributes to actin binding activity. Involved in positive regulation of transcription, DNA-templated and skeletal muscle contraction. Localizes to nucleus and troponin complex. Implicated in distal arthrogryposis type 2B1.
Type: protein-coding
RefSeq Status: REVIEWED
