Disease relevance of ARC6

The ARC6 gene product is related closely to Ftn2, a prokaryotic cell division protein unique to cyanobacteria [1].

High impact information on ARC6

ARC6 is a J-domain plastid division protein and an evolutionary descendant of the cyanobacterial cell division protein Ftn2 [1].
Our evidence would suggest that ARC6 is expressed throughout the vegetative cells of the Arabidopsis seedling with major effects on both the proplastid phenotype and the proplastid population [2].
ARC5 maps to chromosome 3 and ARC11 and ARC6 map approximately 60 cM apart on chromosome 5 [3].

Analytical, diagnostic and therapeutic context of ARC6

During arc6 stomatal guard cell development the perturbation in proplastid population dynamics affects plastid segregation and 30% of stomata lack plastids in one or both guard cells [2].
