Strong cytoplasmic and nuclear immunoreactivity was observed in several cases of testicular cancers while liver cancers showed moderate to strong staining. Remaining cancers were generally weakly stained or negative.
Most cancer tissues showed Weak to moderate cytoplasmic staining, often with a granular pattern. Several pancreatic cancers along with few cases of lung, ovarian and stomach cancers showed strong positivity. Few cases of colorectal cancers displayed additional membranous staining. Several cases of lymphoma, cervix and skin cancers were negative.

Entrez gene summary
The protein encoded by this gene has weak homology to several carbohydrate kinases, a class of proteins involved in the phosphorylation of sugars as they enter a cell, inhibiting return across the cell membrane. Sequence variation between this novel gene and known carbohydrate kinases suggests the possibility of a different substrate, cofactor or changes in kinetic properties distinguishing it from other carbohydrate kinases. The gene resides in a region commonly deleted in cystinosis patients, suggesting a role as a modifier for the cystinosis phenotype. The genomic region is also rich in Alu repetitive sequences, frequently involved in chromosomal rearrangements. [provided by RefSeq, Jul 2008]
