Target Name

TCIM

Target Full Name

Transcriptional and immune response regulator

Target Function

Seems to be involved in the regulation of cell growth an differentiation, may play different and opposite roles depending on the tissue or cell type. May enhance the WNT-CTNNB1 pathway by relieving antagonistic activity of CBY1. Enhances the proliferation of follicular dendritic cells. Plays a role in the mitogen-activated MAPK2/3 signaling pathway, positively regulates G1-to-S-phase transition of the cell cycle. In endothelial cells, enhances key inflammatory mediators and inflammatory response through the modulation of NF-kappaB transcriptional regulatory activity. Involved in the regulation of heat shock response, seems to play a positive feedback with HSF1 to modulate heat-shock downstream gene expression. Plays a role in the regulation of hematopoiesis even if the mechanisms are unknown. In cancers such as thyroid or lung cancer, it has been described as promoter of cell proliferation, G1-to-S-phase transition and inhibitor of apoptosis. However, it negatively regulates self-renewal of liver cancer cells via suppresion of NOTCH2 signaling.

Target Subcellular Location

Cytoplasm. Nucleus, nucleolus. Nucleus speckle. Nucleus.

Target Tissue Specificity

Ubiquitous. Expressed in thyroid papillary carcinoma. Expressed in liver, expression levels decrease in hepatocellular carcinoma. Slightly detected in normal lung, its expression is highly induced in lung cancer cells (at protein level).

Target Research Area

Signal Transduction

Target Synonyms

Target Background

This gene encodes a small, monomeric, predominantly unstructured protein that functions as a positive regulator of the Wnt/beta-catenin signaling pathway. This protein interacts with a repressor of beta-catenin mediated transcription at nuclear speckles. It is thought to competitively block interactions of the repressor with beta-catenin, resulting in up-regulation of beta-catenin target genes. The encoded protein may also play a role in the NF-kappaB and ERK1/2 signaling pathways. Expression of this gene may play a role in the proliferation of several types of cancer including thyroid cancer, breast cancer and hematological malignancies.
