Spermatogenic leucine zipper protein 1

Gene

SPZ1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Transcription factor that binds to the DNA sequence 5'-CANNTG-3'(E box) and the G-box motif. May play an important role in the regulation of cell proliferation and differentiation during spermatogenesis (By similarity).By similarity

Miscellaneous

The helix-loop-helix and basic motifs form a SPZ1 specific bHLH different from the classical one.By similarity
