Function

ARC6_ARATH Component of the plastid division machinery. Involved in the initiation of proplastid and plastid division (including chloroplasts, statoliths and leukoplasts). Promotes the assembly and/or stabilization of the plastid-dividing FtsZ ring, functioning as an antagonistic regulator of FtsZ dynamics against CDP1. Relays plastid division site position between stroma and outer surface via interactions with the stromal FtsZ ring and the outer membrane PDV2 that recruits cytoplasmic ARC5 ring. Required for plastid equatorial positioning of PDV2 and ARC5. May contribute to gravitropism in stems and hypocotyls. Seems to influence stromule (stroma-filled tubular extensions of the plastid envelope membrane) length and frequency.[1] [2] [3] [4] [5] [6] [7] [8]
