 "Abnormal muscle development in the heldup3 mutant of Drosophila
 melanogaster is caused by a splicing defect affecting selected
 troponin I isoforms.";
 Mol. Cell. Biol. 13:1433-1439(1993).
 -!- FUNCTION: Troponin I is the ATPase inhibitory subunit of troponin
     in the thin filament regulatory complex. Involved in the
     development and maintenance of muscle and nervous system. May also
     be involved in the cytoskeletal apparatus.
     {ECO:0000269|PubMed:1899228}.
 -!- SUBUNIT: Binds to actin and tropomyosin.
 -!- ALTERNATIVE PRODUCTS:
     Event=Alternative splicing; Named isoforms=10;
       Comment=Exon 3 is either present or absent, exon 6 has 4
       mutually exclusive forms (6a1, 6a2, 6b1 and 6b2) and C-terminal
       exons 9 and 10 are mutually exclusive.;

 -!- TISSUE SPECIFICITY: All isoforms are expressed in somatic muscle.
     Isoforms containing exon 6a1 (isoforms 1 and 2) are expressed in
     all muscles but highest expression is in abdominal muscle and
     splanchnic muscle of the gut. Isoforms containing exon 6b1
     (isoforms 5, 6, 9 and 10) are highly expressed in the tergal
     depressor of trochanter (TDT) muscle.
     {ECO:0000269|PubMed:7680094}.
 -!- DEVELOPMENTAL STAGE: Isoforms containing exon 3 (isoform 9 and
     isoform 10) are expressed in adults. Isoforms containing exon 6a1
     (isoforms 1 and 2) are expressed at all developmental stages.
     Isoforms containing exon 6a2 (isoforms 3 and 4) are weakly
     expressed in embryos and larvae and very weakly in adults.
     Isoforms containing exon 6b1 (isoforms 5, 6, 9 and 10) are weakly
     expressed in larva and increase during metamorphosis. Isoforms
     containing exon 6b2 (isoforms 7 and 8) are weakly expressed in
     embryos and larvae and at a higher level in adults.
     {ECO:0000269|PubMed:7680094}.
 -!- SIMILARITY: Belongs to the troponin I family. {ECO:0000305}.
