Protein function

Encodes an E3 ubiquitin ligase involed in monoubiquitination of H2B.

Phenotype

/Remarks:
hub1 and hub2 mutations do not lead to additive flowering-time phenotypes. [Cao et al., 2008][Gu et al., 2009]

Overexpressor:
HUB1 overexpressor does not display any flowering-time phenotype. [Dhawan et al., 2009]

Single mutant:
hub1 single mutant is early flowering under both SD and LD conditions. [Cao et al., 2008][Gu et al., 2009][Dhawan et al., 2009]

Function:
E3 ubiquitin-protein ligase that monoubiquitinates H2B to form H2BK143ub1. H2BK143ub1 gives a specific tag for epigenetic transcriptional activation and is also prerequisite for H3K4me and maybe H3K79me. It thereby plays a central role in histone code and gene regulation. Forms a ubiquitin ligase complex in cooperation with the E2 enzyme UBC2/RAD6. Required for the regulation of flowering time and defense against necrotrophic fungal pathogens (PubMed:12535538, PubMed:17329565, PubMed:17329563, PubMed:19286969). Involved in the control of seed dormancy and germination (PubMed:21799800). [Data from UniProt]
