Summary: Enables L-proline transmembrane transporter activity and proline:sodium symporter activity. Involved in L-proline import across plasma membrane and glycine import across plasma membrane. Acts upstream of or within amino-acid betaine transport and proline transmembrane transport. Located in apical plasma membrane. Is expressed in brain; early conceptus; metanephros; and secondary oocyte. Orthologous to human SLC6A20 (solute carrier family 6 member 20). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Data suggest that a high-fat diet induces expression of two amino acid transporters (Slc6a20a, Slc36a1) in intestinal mucosa pointing to a specific and adaptive absorption of some amino acids in high-fat diet-induced obesity and glucose intolerance.
Title: Disturbed intestinal nitrogen homeostasis in a mouse model of high-fat diet-induced obesity and glucose intolerance.
We assessed two candidates for the betaine/proline transporter: SIT1 (IMINO; encoded by Slc6a20a) and PROT (Slc6a7). mRNA from both genes was present in eggs and 1-cell embryos.
Title: SIT1 is a betaine/proline transporter that is activated in mouse eggs after fertilization and functions until the 2-cell stage.
molecular cloning of two mouse homologues corresponding to the single human SLC6A20 gene: these have been named XT3 and XT3s1 [Xt3s1]
Title: Molecular cloning of the mouse IMINO system: an Na+- and Cl--dependent proline transporter.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
