Basic helix-loop-helix leucine zipper transcription factors
Basic helix-loop-helix leucine zipper transcription factors are, as their name indicates, transcription factors containing both Basic helix-loop-helix and leucine zipper motifs.
Additional recommended knowledge
An example is Microphthalmia-associated transcription factor.
