Cotton plasma membrane intrinsic protein
2s (PIP2s) selectively interact to regulate their water channel activities and are required for fibre development.

Trp is a major contributor to the intrinsic protein
fluorescence spectra and has the highest quantum yield of the aromatic amino acids.
An interesting feature of the prokaryotic aquaporins clustering within the AqpN grade is that it contains species associated with nitrite oxidation in soil, which have only a 34% amino acid identity to the major intrinsic protein
of nitrogen-fixing Rhizobium species found in the symbiosomes of root nodules of leguminous plants (Clarke et al., 2014).
The intrinsic protein
fluorescence spectra for native heart CK-MB and rCK-MB2 also are similar (Fig.
The deduced ApAQP protein appears to be phylogenetically related to plant AQPs of the plasma membrane intrinsic protein
type (PIPs) and human water-specific AQPs (Nishihara et al., 2008).

A further understanding of changes in the molecular forces of PSE-like chicken meat intrinsic proteins
during heating process could be useful to explain the mechanisms in the impaired functional properties of PSE-like chicken meat.
The major intrinsic proteins
(MIPs) are a large superfamily of integral membrane proteins present in all biological systems from Archaea and bacteria to eukaryotes (Engel and Stahlberg, 2002; Zardoya, 2005).
