Curator Summary  ? Encodes calcium dependent protein kinase 6 (CPK6), a member of the Arabidopsis CDPK gene family. CDPKs contain an intrinsic Ca2 -activation domain with four EF hand Ca2 -binding sites. CDPKs protein kinases have been proposed to function in multiple plant signal transduction pathways downstream of [Ca2 ]cyt elevations, thus transducing various physiological responses. CPK6 is expressed in both guard cells and mesophyll cells. Functions in guard cell ion channel regulation. ABA and Ca(2 ) activation of slow-type anion channels and, interestingly, ABA activation of plasma membrane Ca(2 )-permeable channels were impaired in independent alleles of single and double cpk3cpk6 mutant guard cells. Furthermore, ABA- and Ca(2 )-induced stomatal closing were partially impaired in these cpk3cpk6 mutant alleles. The protein kinase CPK6 is shown in biochemical assays to be directly activated by elevations in calcium concentrations in the physiological range (Laanements et al., 2013 PlantPhys.; PMID: 23766366). These data correlate with the in vivo function of CPK6 in Ca2 and ABA activation of S-type anion channels (Mori et al., 2006 PLoS Biol.; PMID: 17032064) and the ability of CPK6 to mediate ABA activation of SLAC1 (Brandt et al., 2012 PNAS; PMID: 22689970).  Source: TAIR, Jun 30, 2015.

CPK6 functions in guard cell ion channel regulation and provide genetic evidence for calcium sensors that transduce stomatal ABA signaling. 17032064
AtCPK6 is functionally redundant and a positive regulator involved in the tolerance to salt/drought stress in Arabidopsis. 20217124
These results provide genetic evidence that CPK6 has a different role from CPK3 and functions as a positive regulator of methyl jasmonate signaling in Arabidopsis guard cells. 20978156
CPK6 positively functions in induction by yeast elicitor (YEL) of stomatal closure and inhibition by YEL of light-induced stomatal opening in Arabidopsis. 23922271
(CPK6 and CPK33) are expressed in shoot apical meristem and directly interact with FD, suggesting they have redundant functions 25661797
