Cbs Gene Summary [Rat]
Predicted to enable several functions, including S-adenosyl-L-methionine binding activity; carbon monoxide binding activity; and cystathionine beta-synthase activity. Involved in several processes, including cellular response to hypoxia; hydrogen sulfide biosynthetic process; and transsulfuration. Predicted to be located in nucleus. Predicted to be active in cytoplasm. Biomarker of hyperhomocysteinemia and vitamin B12 deficiency. Human ortholog(s) of this gene implicated in several diseases, including cerebral infarction; homocystinuria; hyperhomocysteinemia; malaria; and neural tube defect. Orthologous to human CBS (cystathionine beta-synthase). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Cbs often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
