Tumor tissues displayed weak to moderate cytoplasmic positivity. A few cases of testicular tumors were strongly positive. Several cases of renal cancers, lymphomas and lung cancers were however negative.
Malignant cells displayed weak to moderate cytoplasmic staining, sometimes with a dot like cytoplasmic appearance.
GENE INFORMATION
Gene name
RNF19A (HGNC Symbol)
Synonyms
DKFZp566B1346, dorfin, RNF19
Description
Ring finger protein 19A, RBR E3 ubiquitin protein ligase (HGNC Symbol)
Entrez gene summary
This gene encodes a member of the ring between ring fingers (RBR) protein family, and the encoded protein contains two RING-finger motifs and an in between RING fingers motif. This protein is an E3 ubiquitin ligase that is localized to Lewy bodies, and ubiquitylates synphilin-1, which is an interacting protein of alpha synuclein in neurons. The encoded protein may be involved in amyotrophic lateral sclerosis and Parkinson's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]
