Primarily involved in epidermal cell differentiation and lipid metabolism.
Critical for vascular development and apical meristem maintenance. hormon.zip
Regulates responses to abiotic stress (drought, cold) and ABA signaling. Involved in light response and auxin-mediated development. HD-Zip III these include: HD-Zip proteins
The leucine zipper motif allows these proteins to form homodimers or heterodimers, which is essential for their function. particularly from the HD-Zip I family
While "hormon.zip" likely refers to the plant-specific HD-Zip proteins, the term generally describes chemical messengers that travel through the bloodstream to regulate vital processes in all living organisms. In humans, these include:
HD-Zip proteins, particularly from the HD-Zip I family, regulate ABA homeostasis, which is vital for responding to abiotic stresses like drought and salinity.
