FunFam 21731: Low density lipoprotein receptor adapter protein 1

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Receptor-mediated endocytosis GO:0006898
An endocytosis process in which cell surface receptors ensure specificity of transport.
