Is predicted to encode a protein with the following domains: Immunoglobulin-like fold; Immunoglobulin subtype 2; Immunoglobulin subtype; Immunoglobulin-like domain superfamily; Immunoglobulin I-set; and Immunoglobulin I-set domain. Is an ortholog of C. elegans
unc-89. In C. elegans,
unc-89 is involved in several processes, including myofibril assembly; pharyngeal gland morphogenesis; and regulation of striated muscle contraction.
