Summary: Enables cystathionine beta-synthase activity. Acts upstream of or within several processes, including endochondral bone morphogenesis; regulation of intracellular signal transduction; and sulfur amino acid metabolic process. Predicted to be located in nucleus. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; connective tissue; nervous system; sensory organ; and skeleton. Used to study homocystinuria and hyperhomocysteinemia. 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, Jan 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

mRNA and Protein(s)

NM_001271353.2 → NP_001258282.1 cystathionine beta-synthase isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (3) uses an alternate splice site in the 5' UTR and lacks an alternate in-frame exon in the 3' coding region compared to variant 1. Both variants 2 and 3 encode the same isoform (2), which is shorter than isoform 1.
