Protein
Ubiquitin carboxyl-terminal hydrolase 36
Organism
Drosophila melanogaster
Length
1038 amino acids
Function
Hydrolase that deubiquitinates polyubiquitinated target proteins including imd (PubMed:19837371, PubMed:19039105). Required for preventing the constitutive activation of the imd/NF-kappa-B (Imd) signaling cascade under unchalleneged conditions (PubMed:19837371, PubMed:25027767). Deubiquitinates imd linked 'Lys-63' chains which leads its proteasomal degradation and consequently down-regulation of the Imd signaling cascade (PubMed:19837371). Removal of the activating 'Lys-63'-linked chains is likely to enable their replacement with 'Lys-48'-linked chains which act as 'tags' the for proteosomal degradation of imd (PubMed:19837371). Required for maintaining multiple types of adult stem cells, including male and female germline, epithelial follicle cell and intestinal stem cells (PubMed:19039105). May function as a transcriptional repressor by continually deubiquiting histone H2B at the promoters of genes critical for cellular differentiation, thereby preventing histone H3 'Lys-4' trimethylation (H3K4me3) (PubMed:19039105). Controls selective autophagy activation by ubiquitinated proteins (PubMed:22622177).
