Presence of CX_2–4 CXφX₈HX₃H sequence in a protein suggest that it is

1. a protein kinase
2. GTP binding protein
3. zinc finger protein
4. lipase

Correct Option: C

A zinc finger protein is a DNA-binding protein domain consisting of zinc fingers ranging from two in the Drosophila regulator ADR1, the more common three in mammalian Sp1 up to nine in TF₁₁₁A. They occur in nature as the part of transcription factors conferring DNA sequence specificity as the DNA-binding domain.
