IPR018456

Source: InterPro

Description

IPR018456 is a PTR2 family proton/oligopeptide symporter, conserved site.

<p>The transport of peptides into cells is a well-documented biological phenomenon which is accomplished by specific, energy-dependent transporters found in a number of organisms as diverse as bacteria and humans. The PTR family of proteins is distinct from the ABC-type peptide transporters and was uncovered by sequence analyses of a number of recently discovered peptide transport proteins [[cite:PUB00003872]]. These proteins that seem to be mainly involved in the intake of small peptides with the concomitant uptake of a proton [[cite:PUB00005425]].</p> <p>These integral membrane proteins are predicted to comprise twelve transmembrane regions.</p> <p>This entry describes two conserved sites. The first conserved site is found within a region that includes the end of the second transmembrane region, a cytoplasmic loop as well as the third transmembrane region. The second conserved site corresponds to the core of the fifth transmembrane region.</p>

GO:0006857
Biological process Oligopeptide transport The directed movement of oligopeptides into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Oligopeptides are molecules that contain a small number (2 to 20) of amino-acid residues connected by peptide linkages.
