**Background of Recombinant Human SLA Protein**
Recombinant human SLA (Src-like adaptor) protein is a synthetic variant of the endogenous SLA protein, a key regulatory molecule involved in signal transduction pathways. Native SLA, primarily expressed in immune cells, acts as an adaptor protein that modulates receptor signaling by interacting with components of the Src kinase family, T-cell receptors (TCRs), and B-cell receptors (BCRs). It plays a critical role in downregulating signaling cascades, thereby maintaining immune homeostasis and preventing hyperactivation.
The recombinant form is engineered using expression systems like *E. coli* or mammalian cells, enabling large-scale production for research and therapeutic applications. Its structure preserves functional domains essential for binding phosphorylated tyrosine residues and mediating protein-protein interactions. Recombinant SLA is widely utilized to study immune regulation, autoimmune disorders, and cancer progression, as dysregulated SLA expression has been linked to pathologies like leukemia and lupus.
Additionally, it serves as a tool for drug screening, aiming to develop therapies targeting SLA-associated pathways. The availability of recombinant SLA ensures standardized, high-purity material for mechanistic studies and translational research, bridging gaps between cellular biology and clinical innovation.
