ram-2 encodes a cuticle collagen that interacts with unc-6 to affect ray cell migration, and interacts with unc-5 and unc-6 to affect embryonic viability; also affects ray morphology in males such that the structural cells and the hypodermis of the rays are swollen in mutants.
Predicted to be a structural constituent of cuticle. Involved in nematode male tail tip morphogenesis and sensory organ development. Predicted to be located in membrane. Predicted to be part of collagen trimer.
