SLC66 Lysosomal amino acid transporters in GtoPdb v.2023.1

Abstract
This is a family of 5 evolutionarily related proteins. Their structural similarities suggest that they are transporters. Biochemical evidence supports transporter activity for SLC66A1 (LAAT1) and SLC66A4 (CTNS; Cystinosin), primarily exporting amino acids from the lysosome to the cytoplasm. The functions of the 3 remaining members of the family are undetermined.
Contents
This is a citation summary for SLC66 Lysosomal amino acid transporters in the
Guide to Pharmacology
database (GtoPdb). It exists purely as an adjunct to the database to
facilitate the recognition of citations to and from the database by
citation analyzers. Readers will almost certainly want to visit the
relevant sections of the database which are given here under database
links.
GtoPdb is an expert-driven
guide to pharmacological targets and the substances that act on them.
GtoPdb is a reference work which is most usefully represented as an
on-line database. As in any publication this work should be
appropriately cited, and the papers it cites should also be
recognized. This document provides a citation for the relevant parts
of the database, and also provides a reference list for the research
cited by those parts. For further details see [2].
Please note that the database version for the citations given in
GtoPdb are to the most recent preceding version
in which the family or its subfamilies and targets were substantially
changed. The links below are to the current version. If you
need to consult the cited version, rather than the most recent version, please contact
the GtoPdb curators.
