About Smo

Chromosome 6: 29,735,502-29,761,364 forward strand.GRCm39:CM000999.3

This gene has 2 transcripts (splice variants), 204 orthologues, 15 paralogues and is associated with 40 phenotypes. Broad expression in ovary adult (RPKM 53.2), limb E14.5 (RPKM 37.8) and 25 other tissues.

Summary

Predicted to enable patched binding activity. Involved in several processes, including animal organ development; regulation of animal organ morphogenesis; and regulation of gene expression. Acts upstream of or within several processes, including animal organ development; positive regulation of cell population proliferation; and regionalization. Located in 9+0 non-motile cilium; ciliary membrane; and cytoplasm. Is expressed in several structures, including 1st branchial arch; 4-cell stage embryo; alimentary system; central nervous system; and genitourinary system. Used to study medulloblastoma and pulmonary emphysema. Human ortholog(s) of this gene implicated in basal cell carcinoma; hepatocellular carcinoma; pancreatic cancer; and pancreatic ductal carcinoma. Orthologous to human Smo (smoothened, Frizzled class receptor). [provided by Alliance of Genome Resources, Apr 2022]
