Summary: Predicted to enable troponin T binding activity. Predicted to contribute to actin binding activity. Predicted to be involved in cardiac muscle contraction; positive regulation of DNA-templated transcription; and skeletal muscle contraction. Predicted to be located in nucleus. Predicted to be part of troponin complex. Is expressed in several structures, including alimentary system; eyelid epithelium; heart; hindlimb muscle; and integumental system. Used to study distal arthrogryposis. Human ortholog(s) of this gene implicated in arthrogryposis multiplex congenita and distal arthrogryposis type 2B1. Orthologous to human TNNI2 (troponin I2, fast skeletal type). [provided by Alliance of Genome Resources, Dec 2024]

GeneRIFs: Gene References Into Functions

What's a GeneRIF?

our findings revealed a new function of tnni2 in the regulation of bone development, and the study of gain-of-function mutation in Tnni2 in transgenic mice opens a new avenue to understand the pathological mechanism of human DA2B disorder.
Title: A gain-of-function mutation in Tnni2 impeded bone development through increasing Hif3a expression in DA2B mice.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
