Gene : AHG2 A. thaliana

Gene ID  ? AT1G55870
Brief Description  Polynucleotidyl transferase, ribonuclease H-like superfamily protein  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? ABA-HYPERSENSITIVE GERMINATION 2 (AHG2); FUNCTIONS IN: ribonuclease activity, nucleic acid binding; INVOLVED IN: response to abscisic acid stimulus, RNA modification, response to stress, response to salicylic acid stimulus; LOCATED IN: nucleus; EXPRESSED IN: 10 plant structures; EXPRESSED DURING: 6 growth stages; CONTAINS InterPro DOMAIN/s: Ribonuclease CAF1 (InterPro:IPR006941), Polynucleotidyl transferase, ribonuclease H fold (InterPro:IPR012337); BEST Arabidopsis thaliana protein match is: Polynucleotidyl transferase, ribonuclease H-like superfamily protein (TAIR:AT3G25430.1).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? Encodes a poly(A)-specific ribonuclease, AtPARN. Expression of AtPARN is upregulated by ABA or stress treatment. Mutant is hypersensitivity to salicylic acid as well as ABA.  Source: TAIR, Jun 30, 2015.

Annotation PubMed Id
AHG2 encodes a poly(A)-specific ribonuclease (AtPARN)that is presumed to function in mRNA degradation. Both upregulation and downregulation of gene expression by AtPARN are crucial for proper ABA, salicylic acid and stress responses. [AHG2] 16359390
A partial defect of AHG2/PARN perturbs mitochondrial function independently in addition to the abscisic acid and salicylic acid responses. 19892832
AHG2 and AGS1 constitute a regulatory system that controls mitochondrial mRNA poly(A) status in Arabidopsis. 23912222
