PM129 clone from Arabidopsis thaliana (PMAT)

entry list
PM129 clone from A. thaliana (PMAT) cDNA, enriched for plasma membrane associated proteins, contains a single continuous open reading frame [77]. The 37 residues before the first of four EF-hand domains may comprise a distinct domain. Each of the linkers 1,2 2,3 and 3,4 is eight residues long. There are three Cys's in the fourth EF-hand and one in the 3,4 linker; a disulfide bond could be formed without distorting the canonical EF-hand. It is strange that domains 1 and 2 of PMAT most closely resemble one another and that domain 4 of PMAT closely resembles domains 1 and 3 of CVP.
