This CCCH zinc finger domain is found in the PAN2-PAN3 deadenylation complex subunit PAN3 from Saccharomyces cerevisiae and related proteins. PAN3 is a regulatory subunit of the PAN2-PAN3 deadenylation complex, which plays a crucial role in mRNA degradation by shortening the poly(A) tails of cytoplasmic mRNAs [1,2]. PAN3 binds directly to RNA through its pseudokinase/C-terminal domain and its N-terminal CCCH zinc finger, which specifically binds to poly(A) RNA [1].	Domain
