In the plant Arabidopsis thaliana, At3g19720 is a gene locus for which there are two gene models, At3g19720.1 and a splice variant At3g19720.2. The protein is also known as Arc5, which stands for "Accumulation and replication of chloroplast 5".

[edit] Properties
Arc5 has 778 amino acids and an estimated molecular weight of 87172 Da. It is a relatively neutral protein, with a pI of 6.7.
[edit] Function
This protein is involved in chloroplast division. It is being studied by people interested in chloroplast morphogenesis.
[edit] Domain structure
The N-terminal domain is homologous to a dynamin-GTPase domain, corresponding to InterPro family IPR001401 and Pfam family PF00350.
[edit] Knockout phenotype
Mutants exhibit fewer and larger chloroplasts.
[edit] Localization and expression
Arc5 is a cytosolic protein, but localizes to the outer ring separating the two daughter chloroplasts during chloroplast division.
[edit] Interactions
Arc5 appears to be recruited to the chloroplast division site by two proteins PDV1 and PDV2.
