Gene: FANCB (FA complementation group B) Homo sapiens
Symbol: FANCB
Name: FA complementation group B
Description: Predicted to be involved in negative regulation of double-strand break repair via homologous recombination; positive regulation of double-strand break repair via homologous recombination; and replication-born double-strand break repair via sister chromatid exchange. Localizes to the Fanconi anaemia nuclear complex. Implicated in Fanconi anemia complementation group B and head and neck squamous cell carcinoma. Biomarker of tongue squamous cell carcinoma.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: FA2; FAAP90; FAAP95; FAB; FACB; Fanconi anemia complementation group B; Fanconi anemia group B protein; Fanconi anemia, complementation group B; fanconi anemia-associated polypeptide of 95 kDa; type 2 Fanconi pancytopenia
