| === Basic information ===
| |
|
| |
| * '''Locus tag:''' BSU15420
| |
|
| |
| ===Phenotypes of a mutant ===
| |
| * Deletion of ''divIVA'' leads to filamentation and polar divisions that in turn cause a minicell phenotype. [http://www.ncbi.nlm.nih.gov/sites/entrez/9219999 PubMed]
| |
| * A ''divIVA'' mutant has a severe [[sporulation]] defect. [http://www.ncbi.nlm.nih.gov/sites/entrez/11445541 PubMed]

| =The protein=
| |
|
| |
| === Basic information/ Evolution ===
| |
|
| |
| * '''Catalyzed reaction/ biological activity:'''
| |
| ** curvature sensitive membrane binding protein that recruits other proteins to the poles and the division septum
| |
| ** DivIVA is required for polar localisation of [[MinC]]-[[MinD]] via [[MinJ]]. [http://www.ncbi.nlm.nih.gov/sites/entrez/19019154 PubMed]
| |
| ** It also recruits [[RacA]] to the distal pole of the prespore [http://www.ncbi.nlm.nih.gov/sites/entrez/12493822 PubMed].
| |
|
| |
| * '''Protein family:''' gpsB family (according to Swiss-Prot)
| |
|
| |
| * '''Paralogous protein(s):''' [[GpsB]]
| |
|
| |
| === Extended information on the protein ===
| |
|
| |
| * '''Kinetic information:'''
| |
|
| |
| * '''[[Domains]]:'''
| |
| ** the first 60 amino acids constitute a conserved lipid binding domain. [http://www.ncbi.nlm.nih.gov/sites/entrez/19478798 PubMed]
| |
| ** the C-terminal domain is less conserved
| |
| ** multimerisation involves two coiled-coil motifs, one in the lipid binding domain, and the other one being present in the helical C-terminal domain {{PubMed|18388125}} {{PubMed|23264578}}
| |
|
| |
| * '''Modification:'''
| |
| ** phosphorylated on Arg-102 {{PubMed|22517742}}
| |
| ** The ''Mycobacterium'' DivIVA homologue Wag31 is phosphorylated at T73 [http://www.ncbi.nlm.nih.gov/sites/entrez/15985609 PubMed]
| |
| ** DivIVA from ''Streptococcus pneumoniae'' is phosphorylated at Threonine 201 by the Ser/Thr protein kinase Sktp1. [http://www.ncbi.nlm.nih.gov/sites/entrez/20453092 PubMed][http://www.ncbi.nlm.nih.gov/sites/entrez/22211696 PubMed]

| |
|
| |
| * '''[[Localization]]:'''
| |
| ** DivIVA forms a ring underneath the invaginating membrane at the site of cell division and is enriched at both cell poles [http://www.ncbi.nlm.nih.gov/sites/entrez/9219999 PubMed].
| |
| ** forms rings at the division septum and patches at the cell poles {{PubMed|22108385}}
| |
| ** membrane targeting requires [[SecA]] {{PubMed|24592260}}
