Protein Name:
Protein SGT1 homolog B
|
UniprotKB/SwissProt ID: Q9SUT5 (Q9SUT5)
Gene Name:
SGT1B
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Involved in plant innate immunity. Essential for race-specific resistance conferred by multiple R genes, including RPP7, recognizing different oomycete pathogen isolates like avirulent Hyaloperonospora arabidopsidis (downy mildew). Contributes additively with RAR1 to RPP5-dependent resistance. Not required for RPM1, RPS2, RPS4 and RPS5-mediated resistance. Functions as a negative regulator of RPS5 accumulation by assisting its degradation. May be involved in heat shock response by associating with HSC70-1 chaperone. Required for the SCF(TIR1)-mediated degradation of Aux/IAA proteins, but maybe not for SCF(TIR1) assembly or binding to its Aux/IAA substrates. Probably required for SCF-mediated ubiquitination, by coupling HSP90 to SCF complex for ubiquitination of HSP90 client proteins. Required for the coronatine/jasmonic acid-mediated signal transduction pathway
