[C.elegansII] Deletions (eg sup-10(n184)) viable, normal muscle; increased lethality of mlc-2(0).Resembles mammalian non-muscle MLC; expressed in both pharynx and body wall. Not transpliced. [Cummins and Anderson 1988; TR]
mlc-1 encodes a muscle regulatory myosin light chain that is nearly identical to MLC-2 and functions redundantly with MLC-2 in the body-wall and in pharyngeal muscle to affect L1 larval viability, elongation, and pharyngeal and body-wall muscle development, and also affects locomotion and growth; expressed in the body-wall muscles, pharyngeal muscles, and vulval muscles.
Predicted to enable myosin heavy chain binding activity. Involved in several processes, including muscle organ development; nematode larval development; and regulation of muscle contraction. Part of muscle myosin complex. Expressed in anal depressor muscle; body wall musculature; pharyngeal muscle cell; pharynx; and vulval muscle. Human ortholog(s) of this gene implicated in distal arthrogryposis type 1C and hypertrophic cardiomyopathy 10. Is an ortholog of human MYL10 (myosin light chain 10); MYL5 (myosin light chain 5); and MYL7 (myosin light chain 7).
