Anti-PTCRA / Pre T-cell antigen receptor alpha

0.5mg/ml if reconstituted with 0.2ml sterile DI water. PTCRA antibody targets Pre T-cell antigen receptor alpha, encoded by the PTCRA gene. Pre T-cell antigen receptor alpha is a type I transmembrane protein that forms an essential component of the pre-T cell receptor (pre-TCR) complex during early T lymphocyte development. Unlike conventional antigen receptors, PTCRA pairs with the T cell receptor beta chain to enable ligand-independent signaling that drives thymocyte maturation.Functionally, Pre T-cell antigen receptor alpha plays a critical role in beta-selection, a developmental checkpoint that ensures productive T cell receptor beta chain rearrangement. Signaling through the pre-TCR complex promotes thymocyte survival, proliferation, and differentiation, while preventing further beta chain recombination. A PTCRA antibody supports research focused on T cell development, immune signaling, and lymphocyte lineage commitment.PTCRA expression is largely restricted to immature thymocytes and is downregulated as T cells progress toward mature alpha-beta T cell receptor expression. Subcellular localization reflects its role as a membrane-associated receptor component, with PTCRA present at the cell surface as part of the pre-TCR complex and within intracellular compartments involved in receptor assembly and trafficking.From a disease-relevance perspective, altered PTCRA expression has been investigated in T cell leukemias and lymphomas, where disruption of normal T cell developmental checkpoints can contribute to malignant transformation. PTCRA is also studied as a marker of early T cell differentiation and thymic activity, providing insight into immune development and dysregulation.At the molecular level, Pre T-cell antigen receptor alpha contains an extracellular immunoglobulin-like domain, a transmembrane region, and a short cytoplasmic tail that contributes to receptor assembly and signaling competence. Regulatory mechanisms controlling PTCRA expression and stability influence pre-TCR signaling strength and developmental outcomes. PTCRA antibody reagents support research applications focused on immune development and T cell receptor signaling pathways, with NSJ Bioreagents providing reagents intended for research use.
