**Background of Recombinant Human TCEAL2 Protein**
The TCEAL2 (Transcription Elongation Factor A-like 2) protein is a member of the TCEAL family, which comprises nuclear proteins involved in transcriptional regulation. Structurally, TCEAL2 contains a conserved TEA domain, enabling DNA binding and interaction with transcriptional machinery. It is broadly expressed in human tissues and plays roles in modulating chromatin dynamics, cellular differentiation, and apoptosis.
Research suggests TCEAL2 acts as a transcriptional modulator, influencing pathways like p53-mediated apoptosis and Wnt/β-catenin signaling. Its dysregulation has been implicated in cancers, particularly ovarian and breast cancers, where it may function as a tumor suppressor or context-dependent oncoprotein. For example, downregulation of TCEAL2 in ovarian cancer correlates with enhanced cell proliferation and metastasis, while overexpression in cervical cancer suppresses malignant phenotypes.
Recombinant human TCEAL2 protein, produced via expression systems like *E. coli* or mammalian cells, retains functional domains for *in vitro* studies. It is widely used to investigate molecular interactions, signaling mechanisms, and therapeutic targeting. Recent studies also explore its potential as a biomarker for cancer prognosis. Despite progress, the precise molecular mechanisms and tissue-specific roles of TCEAL2 remain under investigation, highlighting its significance in both basic and translational research.
