Protein SHORT-ROOT

Gene

SHR

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

Functioni

Transcription factor required for quiescent center cells specification and maintenance of surrounding stem cells, and for the asymmetric cell division involved in radial pattern formation in roots. Essential for both cell division and cell specification. Regulates the radial organization of the shoot axial organs and is required for normal shoot gravitropism. Directly controls the transcription of SCR, and when associated with SCR, of MGP, RLK, TRI, NUC and SCL3.6 Publications

Miscellaneousi

Miscellaneous

Moves via plasmodesmata from the stele into the adjacent cell layer where it locates in the nucleus to controls SCR transcription and endodermis specification. Intact microtubules are required for cell-to-cell trafficking of SHR (PubMed:23294290). This intercellular movement is dependent upon the endosome localized protein SIEL (PubMed:21924907). It is necessary for normal patterning of the root (PubMed:19000160).3 Publications

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.
