AHP2 is present in the nucleus and the cytoplasm, and is involved in light-induced stomata opening.The AHP2 gene is expressed in guard cells.

Title: Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of AHP2, a signal transmitter protein from Arabidopsis thaliana.

ARR1 mediates cold signal via AHP2 (Arabidopsis histidine kinase 2), AHP3, or AHP5.
Title: Arabidopsis response Regulator1 and Arabidopsis histidine phosphotransfer Protein2 (AHP2), AHP3, and AHP5 function in cold signaling.

findings suggest that the presence of Ahp2 protein is necessary for alignment stabilization and synapsis of most chromosome regions but is not required for initial close juxtapositions of homologous chromosomes
Title: Ahp2 (Hop2) function in Arabidopsis thaliana (Ler) is required for stabilization of close alignment and synaptonemal complex formation except for the two short arms that contain nucleolus organizer regions.
