Developmental protein SEPALLATA 1

Gene

SEP1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Probable transcription factor. Functions with SEPALLATA2/AGL4 and SEPALLATA3/AGL9 to ensure proper development of petals, stamens and carpels, and to prevent the indeterminate growth of the flower meristem. Forms a heterodimer via the K-box domain with AGAMOUS, that could be involved in genes regulation during floral meristem development.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
