ubiquitin carboxyl-terminal hydrolase 17-like protein 19 (USP17L19)

Function

• deubiquitinating enzyme
• removes conjugated ubiquitin from specific proteins
• regulatea different cellular processes that may include
  • cell proliferation
  • progression through the cell cycle
  • apoptosis,
  • cell migration
  • cellular response to viral infection
• thiol-dependent hydrolysis of ester, thioester, amide, peptide & isopeptide bonds formed by the C-terminal Gly of ubiquitin

Structure

• belongs to the peptidase C19 family, USP17 subfamily

Compartment

• nucleus (putative)
• endoplasmic reticulum (putative)

Genetics

• the RS447 megasatellite DNA is a highly polymorphic conserved tandem repetitive sequence which contains a copy of the USP17 gene

it is present with an interindividual variation in copy number, ranging from 20 to 103, & can be found in the genome on chromosome 4 & chromosome 8

the high similarity between the UPS17-like genes makes it impossible to specifically assign data to a particular gene of the family

More general terms

• ubiquitin C-terminal hydrolase
• nuclear protein
