A postdoctoral position is available for a period=20
of up to three years to study the regulation and=20
functions of Arabidopsis protein phosphatase 2A=20
(PP2A).  PP2A is an abundant, ubiquitous and=20
highly conserved serine/threonine protein=20
phosphatase with broad substrate specificity and=20
a diverse repertoire of cellular functions.  The=20
RCN1 gene encodes a regulatory A subunit of PP2A,=20
and loss of RCN1 function leads to reduced PP2A=20
activity, alterations in polar auxin transport=20
and pleiotropic effects on plant growth.=20
Mutations in the RCN1 paralogs PP2AA2 and PP2AA3=20
have little effect on overall PP2A activity, but=20
functions of the isoforms encoded by these genes=20
are unmasked in the rcn1 mutant background.=20
Currently we seek to define the molecular basis=20
for functional specialization of A subunit=20
