Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables several functions, including cholesterol-protein transferase activity; laminin-1 binding activity; and patched binding activity. Involved in several processes, including hemopoiesis; positive regulation of T cell activation; and regulation of smooth muscle cell differentiation. Acts upstream of or within several processes, including nervous system development; respiratory system development; and tube morphogenesis. Located in several cellular components, including cell surface; extracellular space; and membrane raft. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Used to study brachydactyly type A1; holoprosencephaly 3; and nevoid basal cell carcinoma syndrome. Human ortholog(s) of this gene implicated in several diseases, including Hirschsprung's disease; holoprosencephaly (multiple); hypoplastic or aplastic tibia with polydactyly; middle cerebral artery infarction; and polydactyly (multiple). Orthologous to human SHH (sonic hedgehog signaling molecule). PHENOTYPE: Heterozygotes exhibit shortening of all digits, holes between the frontal bones, dyssymphyses between cervical vertebrae and bony plates over many ribs. Homozygotes usually die before E12, are short-limbed dwarfs and lack forefeet, hindfeet, eyes, ears, external genitalia and a mouth. [provided by MGI curators] |
