Enables

This protein enables 2 target(s):

Target	Category	Definition
protein binding	molecular function	Binding to a protein. [GOC:go_curators]
bile acid:sodium symporter activity	molecular function	Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: bile acid(out) + Na+(out) = bile acid(in) + Na+(in). [TC:2.A.28.-.-]

Located In

This protein is located in 2 target(s):

Target	Category	Definition
plasma membrane	cellular component	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363]
microvillus	cellular component	Thin cylindrical membrane-covered projections on the surface of an animal cell containing a core bundle of actin filaments. Present in especially large numbers on the absorptive surface of intestinal cells. [ISBN:0815316194]

Active In

This protein is active in 1 target(s):

Target	Category	Definition
apical plasma membrane	cellular component	The region of the plasma membrane located at the apical end of the cell. [GOC:curators]

Involved In

This protein is involved in 4 target(s):

Target	Category	Definition
sodium ion transport	biological process	The directed movement of sodium ions (Na+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:ai]
response to bacterium	biological process	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a bacterium. [GOC:hb]
bile acid and bile salt transport	biological process	The directed movement of bile acid and bile salts into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:dph, GOC:krc, PMID:12663868, PMID:14699511]
transmembrane transport	biological process	The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. [GOC:dph, GOC:jid]
