Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables cargo receptor activity. Involved in cobalamin transport. Acts upstream of or within regulation of vitamin metabolic process. Is active in plasma membrane. Is expressed in several structures, including brain; genitourinary system; heart; immune system; and liver. Used to study methylmalonic acidemia due to transcobalamin receptor defect. Human ortholog(s) of this gene implicated in methylmalonic acidemia due to transcobalamin receptor defect. Orthologous to human CD320 (CD320 molecule).
