RALF1

Gene
RALF1
Protein
Protein RALF-like 1
Organism
Arabidopsis thaliana
Length
120 amino acids
Function
Cell signaling peptide that may regulate plant stress, growth, and development. Mediates a rapid alkalinization of extracellular space by mediating a transient increase in the cytoplasmic Ca(2+) concentration leading to a calcium-dependent signaling events through a cell surface receptor and a concomitant activation of some intracellular mitogen-activated protein kinases. Mostly active in roots. Prevents plant growth (e.g. root and leaf length). Suppresses cell elongation of the primary root by activating the cell surface receptor FER and triggering phosphorylation of AHA2 and subsequent extracellular alkalinization.
Similarity
Belongs to the plant rapid alkalinization factor (RALF) family.
