Taxonomic identifier

44689 [NCBI]

Taxonomic lineage

Eukaryota › Amoebozoa › Mycetozoa › Dictyosteliida › Dictyostelium

Protein attributes

Sequence length	698 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Couples activated G protein to adenylyl cyclase signal transduction from surface cAMP receptor. Pianissimo a cytosolic regulator and CRAC, are both essential for activation of the enzyme adenylyl cyclase. Pianissimo and CRAC do not function redundantly. Both proteins are integral components of the adenylyl cyclase activation pathway.
Subcellular location	Cytoplasm.
Developmental stage	Tightly developmentally regulated.
Disruption phenotype	dagA and piaA double mutants require both proteins for reconstitution and activation of adenylyl cyclase.
Sequence similarities	Contains 1 PH domain.
