NCBI Protein Information
Homeobox-leucine zipper family protein / lipid-binding START domain-containing protein
NCBI Summary
Encodes a homeobox protein similar to GL2. It is expressed in both the apical and basal daughter cells of the zygote as well as their progeny. Expression is detected starting the two-celled stage of embryo development and is later restricted to the outermost, epidermal cell layer from its inception. Its promoter is highly modular with each region contributing to specific aspects of the gene's spatial and temporal expression. Double mutant analysis with PDF2, another L1-specific gene, suggests that their functions are partially redundant and the absence of both of the genes result in abnormal shoot development.

UniProt Comments
Probable transcription factor involved in cell specification and pattern formation during embryogenesis. Binds to the L1 box DNA sequence 5'-TAAATG[CT]A-3'. Plays a role in maintaining the identity of L1 cells, possibly by interacting with their L1 box or other target-gene promoters. Functionally redundant to PDF2.
