What's a GeneRIF?

Data suggest functionality for mutant R171 in stabilizing the inactive arrestin-1 conformation as well as the rhodopsin-arrestin-1 complex.
Title: Arrestin-1 engineering facilitates complex stabilization with native rhodopsin.
Data indicate molecular dynamics simulations and site-directed fluorescence experiments on arrestin-1 interactions with rhodopsin, showing that loops within the C-edge of arrestin function as a membrane anchor.
Title: C-edge loops of arrestin function as a membrane anchor.
Conformational changes are involved in the arrestin-rhodopsin binding interface through multiple docking modes.
Title: Rhodopsin TM6 can interact with two separate and distinct sites on arrestin: evidence for structural plasticity and multiple docking modes in arrestin-rhodopsin binding.
K2A mutations in arrestin-1, -2, and -3 significantly reduced their binding to active phosphorhodopsin.
Title: Role of receptor-attached phosphates in binding of visual and non-visual arrestins to G protein-coupled receptors.
maintenance of low levels of the active monomer is the biological role of arrestin-1 self-association
Title: Robust self-association is a common feature of mammalian visual arrestin-1.
We hypothesize that, although arrestin requires at least a single Rho*P to bind the membrane, a single arrestin can actually interact with a pair of receptors
Title: Arrestin-rhodopsin binding stoichiometry in isolated rod outer segment membranes depends on the percentage of activated receptors.
variant form of arrestin-1 binds rod outer segment membranes
Title: A variant of arrestin-1 binds rod outer segment membranes in a light-independent manner.
Alpha-helix I plays an indirect role in receptor binding, likely keeping beta-strand I, which carries several phosphate-binding residues, in a position favorable for its interaction with receptor-attached phosphates.
Title: The role of arrestin alpha-helix I in receptor binding.
Models suggest that the phosphorylated carboxy-terminal region of rhodopsin, Rh(330-348), undergoes significant conformational changes and becomes structured upon binding to arrestin.
Title: The arrestin-bound conformation and dynamics of the phosphorylated carboxy-terminal region of rhodopsin.
arrestin and p44 bind differently to different phosphorylated rhodopsin species and that this may be due to a structural difference between p44's and arrestin's basal states.
Title: Differential phosphorylation of the rhodopsin cytoplasmic tail mediates the binding of arrestin and its splice variant, p44.

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.
