This domain is found at the C-terminal end of human Protein lin-28 homolog A (Lin-28A), an RNA-binding protein that inhibits processing of pre-let-7 miRNAs and regulates translation of mRNAs that control developmental timing, pluripotency and metabolism. This interaction requires the zinc-knuckle domains of Lin-28A [1-3]. This entry represents the second of these domains.	Domain

The zinc knuckle is a zinc binding motif composed of the the following CX2CX4HX4C where X can be any amino acid. The motifs are mostly from retroviral gag proteins (nucleocapsid). Prototype structure is from HIV. Also contains members involved in eukaryotic gene regulation, such as C. elegans GLH-1. Structure is an 18-residue zinc finger.	Domain
