Function

edit

Cubilin (CUBN) acts as a receptor for intrinsic factor-vitamin B12 complexes. The role of receptor is supported by the presence of 27 CUB domains. Cubilin shows a restricted mode of expression according to protein profiling and transcriptomics analyses,[8] and is essentially only present in the kidneys and small intestine.[9] Mutations in CUBN may play a role in autosomal recessive megaloblastic anemia.[7] A complex of amnionless and cubilin forms the cubam receptor.

Clinical significance

edit

Cubilin is a potential diagnostic and prognostic cancer biomarker for kidney cancer.[10] Based on patient survival data, high levels of cubilin in tumor cells is a favourable prognostic biomarker in renal cell carcinoma.[11][12]
