UCHL1

UCHL1

A gene on chromosome 4p14 that encodes a ubiquitin-protein hydrolase, involved both in processing of ubiquitin precursors and ubiquitinated proteins, which recognises and hydrolyses a peptide bond at the C-terminal glycine of ubiquitin. UCHL1 also binds free monoubiquitin and may prevent its degradation in lysosomes.

UCHL1 is a specific marker identified for spermatogonial and progenitors cells, but not for differentiated spermatogonia or sertoli cells.
Gene Expression: In this study, we specifically applied UCHL1 for the identification of human germ stem cells.
Gene expression: RT-PCR was performed to confirm the expression of spermatogonial specific gene UCHL1 (ubiquitin carboxyl-terminal esterase L1; also known as protein gene product 9.
We could characterize them by the expression of a specific marker, UCHL1, that had been proved earlier as a germ stem cell marker in many species (12).
UCHL1 is a deubiquitinating enzyme that regenerates monoubiquitin from ubiquitin-protein complexes.
Of these 475 genes, UCHL1 on chromosome arm 4p was methylated in all 42 pancreatic cancers studied.
Other genes identified in precursor lesions include PENK, CDKN2A/p16, STK11/LKB1, SPARC, SFRP1/SARP2 (chromosome arm 8p), TSLC1, RELN (chromosome arm 7q), TFPI2, CLDN5 (chromosome arm 22q), and UCHL1 in IPMNs (37,122,123); PENK, CDKN2A/p16, CLDN5, NPTX2, RPRM, SFRP1/SARP2, and LHX1 (chromosome arm 11p) in PanINs (117,118,124); and CDKN2A/p16 in MCNs.
