Distinct cytoplasmic and membranous expression in lymphoid tissues, astrocytes, mesenchymal cells, epidermal Langerhans cells and fractions of glandular cells.
ANTIBODY IHC RELIABILITY
Data reliability description
Antibody staining consistent with RNA expression data.
Among tumors, moderate to strong cytoplasmic and membranous immunoreactivity was observed in malignant melanomas and in some malignant gliomas, endometrial cancers and renal cancers. Other malignant tissues were in general negative.
Melanomas, lymphomas, renal, thyroid and endometrial cancers along with a few cases of gliomas, lung, ovarian and squamous cell carcinomas exhibited moderate to strong cytoplasmic and/or membranous positivity. Remaining cancer tissues were mainly negative.

Entrez gene summary
This gene encodes a member of the intermediate filament family. Intermediate filamentents, along with microtubules and actin microfilaments, make up the cytoskeleton. The protein encoded by this gene is responsible for maintaining cell shape, integrity of the cytoplasm, and stabilizing cytoskeletal interactions. It is also involved in the immune response, and controls the transport of low-density lipoprotein (LDL)-derived cholesterol from a lysosome to the site of esterification. It functions as an organizer of a number of critical proteins involved in attachment, migration, and cell signaling. Mutations in this gene causes a dominant, pulverulent cataract.[provided by RefSeq, Jun 2009]
