tni-4 encodes one of the four elegans troponin I proteins; tni-4 is required for the normal development of the pharynx during embryonic development; TNI-4 interacts only with the pharyngeal troponin C; tni-4 is expressed exclusively in the pharyngeal muscles.
Enables troponin C binding activity. Involved in embryo development and pharyngeal pumping. Located in sarcomere. Expressed in pharyngeal muscle cell and pharynx. Human ortholog(s) of this gene implicated in several diseases, including arthrogryposis multiplex congenita; distal arthrogryposis type 2B1; and intrinsic cardiomyopathy (multiple). Is an ortholog of human TNNI1 (troponin I1, slow skeletal type); TNNI2 (troponin I2, fast skeletal type); and TNNI3 (troponin I3, cardiac type).

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
