BTK, Human (Active, sf9, GST, C481S)

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, C481S) is the recombinant human-derived BTK protein, expressed by Sf9 insect cells, with N-GST labeled tag.
