The Phox Homology domain, a phosphoinositide binding module; The PX domain is a phosphoinositide (PI) binding module involved in targeting proteins to membranes. Proteins containing PX domains interact with PIs and have been implicated in highly diverse functions such as cell signaling, vesicular trafficking, protein sorting, lipid modification, cell polarity and division, activation of T and B cells, and cell survival. Many members of this superfamily bind phosphatidylinositol-3-phosphate (PI3P) but in some cases, other PIs such as PI4P or PI(3,4)P2, among others, are the preferred substrates. In addition to protein-lipid interaction, the PX domain may also be involved in protein-protein interaction, as in the cases of p40phox, p47phox, and some sorting nexins (SNXs). The PX domain is conserved from yeast to humans and is found in more than 100 proteins. The majority of PX domain-containing proteins are SNXs, which play important roles in endosomal sorting. The actual alignment was detected with superfamily member cd07301: Pssm-ID: 470617 Cd Length: 112 Bit Score: 41.33 E-value: 2.16e-05

The phosphoinositide binding Phox Homology domain of Sorting Nexin 21; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. Some SNXs are localized in early endosome structures such as clathrin-coated pits, while others are located in late structures of the endocytic pathway. SNX21, also called SNX-L, is distinctly and highly-expressed in fetal liver and may be involved in protein sorting and degradation during embryonic liver development.

The phosphoinositide binding Phox Homology domain of Sorting Nexins 20 and 21; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. This subfamily consists of SNX20, SNX21, and similar proteins. SNX20 interacts with P-Selectin glycoprotein ligand-1 (PSGL-1), a surface-expressed mucin that acts as a ligand for the selectin family of adhesion proteins. It may function in the sorting and cycling of PSGL-1 into endosomes. SNX21, also called SNX-L, is distinctly and highly-expressed in fetal liver and may be involved in protein sorting and degradation during embryonic liver development.
