NCBI Protein Information
stomagen
NCBI Summary
Encodes a cysteine-rich peptide, a secretory factor that is produced in the mesophyll cells and acts on the epidermis to increase stomatal formation. Its mature form is a 45-aa peptide with three intramolecular disulfide bonds. It is proposed that STOMAGEN increases stomatal number by competing with two negative regulators of stomatal density, EPF1 and EPF2, possibly through direct interaction with the receptor-like protein TMM. Its transcript levels change after inducing MUTE expression in a mute background.

UniProt Comments
Stomagen: Positively regulates stomatal density and patterning. Acts by competing with EPF2 (AC Q8LC53) for the same receptors, ERECTA (AC Q42371) and TMM (AC Q9SSD1). Not cleaved by the protease CRSP (AC Q9LNU1) (PubMed:25043023).
