Malignant melanomas, breast, thyroid, testicular, urothelial and renal cancers showed moderate to strong cytoplasmic and nuclear positivity. Ovarian and endometrial cancers were weakly to moderately stained. The remaining cancers were mainly negative.
Malignant tissues showed weak to moderate nuclear and occasional cytoplasmic staining. Endometrial, ovarian and thyroid cancers displayed moderate nuclear and cytoplasmic staining. Malignant lymphomas, prostate, gastric and liver cancers were weakly stained or negative.

Description
S100 calcium binding protein A13 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein is widely expressed in various types of tissues with a high expression level in thyroid gland. In smooth muscle cells, this protein co-expresses with other family members in the nucleus and in stress fibers, suggesting diverse functions in signal transduction. Multiple alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]
