DEK504 - Plant Editosome Database - BIG Data Center

Summary

Editing Factor:	DEK504
Synonym:	Defective Kernel 504
Description:	Dek504 encodes an E+-type PPR protein targeted to the mitochondria, which is required for RNA editing of mitochondrial NADH dehydrogenase 3 at the nad3-317 and nad3-44 sites; Biochemical analysis of mitochondrial protein complexes revealed a significant reduction in the mitochondrial NADH dehydrogenase complex I activity, indicating that the alteration of the amino acid sequence at nad3-44 and nad3-317 through RNA editing is essential for NAD3 function
Protein Family:	PPR
Subclass:	E+
Construct Structure:	PLS-E1-E2-E+
Gene ID & Species:	Zm00001d022394 (Zea mays)
Edited Gene(s):	nad3
Editing Type(s):	C-to-U (4)
Publication(s):	[1] Encodes a Mitochondrion-Targeted E+-Type Pentatricopeptide Repeat Protein Essential for RNA Editing and Seed Development in Maize., International journal of molecular sciences, 2022. [PMID=35269656]
