Supplementary information

CTBP2 also known as C-terminal binding protein 2 is a transcriptional co-repressor involved in regulating gene expression. It is a protein with a molecular mass of approximately 48 kDa. CTBP2 is expressed in various tissues with high levels in neural muscular and epithelial cells. Mechanically CTBP2 operates by interacting with transcription factors and histone-modifying enzymes modulating chromatin structure to control access to DNA.
Biological function summary

CTBP2 plays a significant role in cellular processes such as development and differentiation. It frequently acts as part of multi-protein complexes interacting with diverse partners to facilitate transcriptional repression. These interactions are essential for balancing gene activity ensuring appropriate tissue development and function. CTBP2 influences cellular dynamics by regulating target genes implicated in growth survival and metabolic pathways.

Pathways

CTBP2 integrates into significant signaling pathways like Wnt and TGF-beta where it reinforces regulatory control by interacting with critical factors such as beta-catenin or Smad proteins. It collaborates with other proteins like CTBP1 dictating cellular responses and influencing pathophysiological processes. By coordinating these pathways CTBP2 supports cellular homeostasis impacting tissues in response to external and internal cues.

CTBP2 has associations with cancer and neurodegenerative diseases. Its overexpression or altered activity links to cancer progression as it promotes a transcriptional environment conducive to tumor growth. Proteins such as E-cadherin connect with CTBP2 in metastasis exemplifying its role in cancer cell dissemination. Additionally changes in CTBP2 function relate to neurodegenerative conditions affecting nerve cell survival and synaptic activity pointing to its involvement in neuronal health and disease mechanisms.
