Gene

A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...

.

This gene encodes a member of the sorting nexin family, a diverse group of cytoplasmic and membrane-associated proteins involved in endocytosis of plasma membrane receptors and protein trafficking through these compartments. All members of this protein family contain a phosphoinositide binding domain (PX domain

PX domain

The PX domain is a phosphoinositide-binding structural domain involved in targeting of proteins to cell membranes.This domain was first found in P40phox and p47phox domains of NADPH oxidase...

5-HT4 receptor

5-hydroxytryptamine receptor 4 is a protein that in humans is encoded by the HTR4 gene.- Location :The receptor is located in the alimentary tract, urinary bladder, heart and adrenal gland as well as the central nervous system ....

Endosome

In biology, an endosome is a membrane-bound compartment inside eukaryotic cells. It is a compartment of the endocytic membrane transport pathway from the plasma membrane to the lysosome. Molecules internalized from the plasma membrane can follow this pathway all the way to lysosomes for...
