At1g64580 Antibody

Target Protein: At1g64580

The At1g64580 gene encodes a pentatricopeptide repeat (PPR) superfamily protein, which is involved in RNA editing, splicing, and stabilization in chloroplasts or mitochondria . PPR proteins are characterized by tandem repeats of 35 amino acids that form RNA-binding domains, enabling sequence-specific interactions with organellar transcripts.

Subcellular Localization Studies

At1g64580 is predicted to localize to mitochondria or plastids, as shown in systematic studies of Arabidopsis PPR proteins :

This dual localization suggests roles in both mitochondrial and chloroplast RNA processing.
