Is predicted to encode a protein with the following domains: Immunoglobulin I-set domain; Immunoglobulin I-set; Immunoglobulin subtype; Leucine-rich repeat N-terminal domain; Immunoglobulin-like fold; Immunoglobulin domain; Leucine-rich repeat; Leucine-rich repeat, typical subtype; Immunoglobulin subtype 2; Leucine rich repeat; Leucine-rich repeat domain superfamily; and Immunoglobulin-like domain superfamily. Is an ortholog of C. elegans sma-10. In C. elegans, sma-10 is involved in several processes, including positive regulation of transforming growth factor beta receptor signaling pathway; regulation of mesodermal cell fate specification; and transforming growth factor beta receptor signaling pathway.
