Btk-type zinc finger

Btk-type zinc fingers are a specific type of zinc finger motif that are commonly found in various proteins, especially in the context of developmental biology and the regulation of gene expression. The term "Btk" refers to Bruton's tyrosine kinase, an enzyme important in the signaling pathways of B cells, and this type of zinc finger is named after it due to its identification in proteins associated with cellular signaling.
