A zinc finger is a small protein structural motif that is characterized by the coordination of one or more zinc ions (Zn²⁺) in order to stabilize the fold. Originally coined to describe the finger-like appearance of a hypothesized structure from Xenopus laevis transcription factor IIIA, the zinc finger name has now come to encompass a wide variety of differing protein structures. Xenopus laevis TFIIIA was originally demonstrated to contain zinc and require the metal for function in 1983, the first such reported zinc requirement for a gene regulatory protein. It often appears as a metal-binding domain in multi-domain proteins.
