Most malignant tissues exhibited moderate cytoplasmic and occasional membranous positivity. Additional nuclear positivity was observed in breast, urothelial cancers, carcinoid and melanoma. Several cases of pancreatic cancer along with rare colorectal, cervical, thyroid, lung, stomach and liver cancers showed strong positivity. The majority of testis, renal, endometrial cancers and lymphoma were weakly stained or negative.

Entrez gene summary
Two types of spliceosomes catalyze splicing of pre-mRNAs. The major U2-type spliceosome is found in all eukaryotes and removes U2-type introns, which represent more than 99% of pre-mRNA introns. The minor U12-type spliceosome is found in some eukaryotes and removes U12-type introns, which are rare and have distinct splice consensus signals. The U12-type spliceosome consists of several small nuclear RNAs and associated proteins. This gene encodes a 25K protein that is a component of the U12-type spliceosome. [provided by RefSeq, Apr 2010]
