NCBI Protein Information
homeobox knotted-like protein
NCBI Summary
A member of class I knotted1-like homeobox gene family (together with KNAT2). Similar to the knotted1 (kn1) homeobox gene of maize. Normally expressed in the peripheral and rib zone of shoot apical meristem but not in the leaf primordia. It is also expressed in the fourth floral whorl, in the region that would become style, particularly in the cell surrounding the transmitting tissue. No expression was detected in the first three floral whorls. Expression is repressed by auxin and AS1 which results in the promotion of leaf fate.

UniProt Comments
May play a role in meristem function, and may be involved in maintaining cells in an undifferentiated, meristematic state, and its expression disappears at the same time the shoot apex undergoes the transition from vegetative to reproductive development (PubMed:11934861). Positive regulator of LATERAL ORGAN BOUNDARIES (LOB) (PubMed:11934861). Probably binds to the DNA sequence 5'-TGAC-3' (PubMed:11934861). Able to traffic from the L1 to the L2/L3 layers of the meristem, presumably through plasmodesmata (PubMed:12900451).
