BTK Protein, Human (Active, sf9, GST)
The BTK protein is a key non-receptor tyrosine kinase that is essential for B lymphocyte development and signaling. After BCR activation, BTK initiates a cascade reaction, phosphorylates PLCG2 and activates downstream pathways, affecting calcium mobilization and PKC activation. BTK Protein, Human (Active, sf9, GST) is the recombinant human-derived BTK protein, expressed by Sf9 insect cells, with N-GST labeled tag.

Biological Activity
Description
The BTK protein is a key non-receptor tyrosine kinase that is essential for B lymphocyte development and signaling. After BCR activation, BTK initiates a cascade reaction, phosphorylates PLCG2 and activates downstream pathways, affecting calcium mobilization and PKC activation. BTK Protein, Human (Active, sf9, GST) is the recombinant human-derived BTK protein, expressed by Sf9 insect cells, with N-GST labeled tag.
Background
BTK Protein, a non-receptor tyrosine kinase, is indispensable for B lymphocyte development, differentiation, and signaling. Upon antigen binding to the B-cell antigen receptor (BCR), BTK triggers a signaling cascade leading to B-cell activation, phosphorylating PLCG2 and initiating downstream pathways involving calcium mobilization and protein kinase C (PKC) activation. Serving as a platform for diverse signaling proteins, BTK is implicated in cytokine receptor signaling pathways and is crucial in innate and adaptive immunity, particularly within the Toll-like receptors (TLR) pathway. It plays a critical role in regulating TLR9 activation in splenic B-cells and induces the activity of NF-kappa-B, contributing to the transcriptional regulation of numerous genes. Additionally, BTK activates NLRP3 inflammasome assembly, phosphorylates transcription factor GTF2I, and is involved in apoptosis regulation, highlighting its multifaceted functions in immune response and cellular processes.
