Basic leucine-zipper, C-terminal (IPR020983)

Short name: Basic_leucine-zipper_C

Overlapping homologous superfamilies


Domain relationships



Basic leucine-zipper (bZIP) proteins are found in eukaryotes. They are typically between 174 and 411 amino acids in length. Various bZIP proteins have been found and shown to play a role in seed-specific gene expression. bZIP binds to the alpha-globulin gene promoter, but not to promoters of other major storage genes such as glutelin, prolamin and albumin [PMID: 9049271].

This entry represents a C-terminal domain found in bZIP proteins. It is found in association with PF00170. There is a conserved KVK sequence motif and a single completely conserved residue K that may be functionally important.
