Disease relevance of PMP1

Interestingly, overexpression of Prz1 did not suppress the Cl(-) hypersensitivity of calcineurin deletion, and overexpression of Pmp1 MAPK phosphatase suppressed the Cl(-) hypersensitivity of calcineurin deletion but not the Ca(2+) hypersensitivity of prz1 deletion [1].

High impact information on PMP1

The two proteolipids differ at residue 21, which is an alanine in PMP1 and a serine in PMP2 [2].
A small proteolipid called PMP1 is associated with yeast plasma membrane H(+)-ATPase (Navarre, C., Ghislain, M., Leterme, S., Ferroud, C., Dufour, J.-P., and Goffeau, A. (1992) J. Biol. Chem. 267, 6425-6428) [2].
The polypeptide lacks the first two NH2-terminal amino acids as compared with the deduced sequence of the PMP1 gene (for plasma membrane proteolipid) isolated by hybridization with an oligonucleotide probe corresponding to an internal amino acid sequence of the proteolipid [3].
Mutational analysis and (1)H NMR experiments were therefore performed on a synthetic PMP1 fragment using DPC-d(38) micelles as a membrane-like environment, in the presence of small amounts of POPS [4].
Protonated DPC, DMPC and DMPS were incorporated in deuterated micelles containing the PMP1 fragment for studying lipid-peptide interactions [5].

Associations of PMP1 with chemical compounds

PMP1 18-38, a yeast plasma membrane protein fragment, binds phosphatidylserine from bilayer mixtures with phosphatidylcholine: a (2)H-NMR study [6].

Analytical, diagnostic and therapeutic context of PMP1

From POPS titration experiments monitored by a full set of one- and two-dimensional NOESY spectra, the association between the phospholipids and the PMP1 peptide has been followed [4].
To investigate the molecular basis of the PMP1 biological function, the conformational properties of a synthetic PMP1 fragment, A18-F38, comprising the predicted C-terminal cytoplasmic domain and a part of the transmembrane anchor have been studied by 1H- and 2H-NMR spectroscopies [5].
Time-resolved anisotropy measurements were consistent with PMP1 fragment immobilization within peptide-detergent complexes [7].
