Cyclic AMP-responsive element-binding protein 3-like protein 4 (Creb3l4)

Transcriptional activator that may play a role in the unfolded protein response of the testis. Proposed to be involved in spermiogenesis.

May be involved in regulating the maturation of sperm head nuclei. Alternatively suggested to be a paternally delivered transcription factor that may function in early zygotic gene activation.
