Description
Covalent attachment of the C-terminus of ubiquitin to cellular proteins plays a role in a variety of cellular processes. Ubiquitin C-terminal hydrolysis is catalyzed by deubiquitinating (DUB) enzymes and is necessary for several functions, including liberation of monomeric ubiquitin from the precursors encoded by ubiquitin genes and recycling of ubiquitin monomers. There are 2 distinct families of DUBs, ubiquitin-specific proteases (UBPs) and ubiquitin C-terminal hydrolases (UCHs). Mayer and Wilkinson (1989) identified 4 distinct UCH activities from bovine thymus. All 4 were thiol proteases and had high-affinity binding sites for ubiquitin. Wilkinson et al. (1989) purified the predominant isozyme, UCHL3, and raised antibodies against it. By screening a human B-cell expression library with the antibodies, the authors isolated cDNAs encoding human UCHL3. Sequence comparisons revealed that the sequence of the predicted 230-amino acid human UCHL3 protein is 54% identical to that of UCHL1.

Background
UCHL3 is a deubiquitinating enzyme involved in ubiquitin recycling and protein turnover, ensuring cellular protein quality control and homeostasis. It cleaves ubiquitin precursors and removes ubiquitin chains from target proteins, preventing their premature degradation by the proteasome. UCHL3 is ubiquitously expressed and plays roles in DNA repair, apoptosis, and embryonic development. It is particularly essential for spermatogenesis, where it regulates chromatin remodeling and germ cell differentiation. Loss of UCHL3 function is associated with impaired cellular proteostasis, genomic instability, and reproductive defects. Studies show its involvement in tumor progression, where dysregulation of UCHL3 alters protein degradation pathways, contributing to cancer cell survival. Knockout models exhibit defects in germ cell development, growth retardation, and increased sensitivity to cellular stress, underscoring its importance in ubiquitin regulation, cellular stability, and reproductive biology.
