UniProt functional annotation for Q9GZ28



	UniProt functional annotation for Q9GZ28

UniProt code: Q9GZ28.

Organism: Anemonia sulcata (Mediterranean snakelocks sea anemone).

Taxonomy: Eukaryota; Metazoa; Cnidaria; Anthozoa; Hexacorallia; Actiniaria; Actiniidae; Anemonia.

Function: Pigment protein that is intensely purple in color. {ECO:0000269|PubMed:10852900}.

Biophysicochemical properties: Absorption: Abs(max)=572 nm; Note=Exhibits a smaller absorbance peak at 530 nm. The wild-type has a very weak fluorescence emission spectrum which peaks at 595 nm.;

Tissue specificity: Tentacle tips. {ECO:0000269|PubMed:10852900}.

Ptm: Contains a chromophore consisting of modified amino acid residues. The chromophore is formed by autocatalytic backbone condensation between Xaa-N and Gly-(N+2), oxidation of Tyr-(N+1) to didehydrotyrosine, and formation of a double bond to the alpha-amino nitrogen of residue Tyr-(N+1). Maturation of the chromophore requires nothing other than molecular oxygen. {ECO:0000305}.

Biotechnology: Fluorescent proteins have become a useful and ubiquitous tool for making chimeric proteins, where they function as a fluorescent protein tag. Typically they tolerate N- and C-terminal fusion to a broad variety of proteins. They have been expressed in most known cell types and are used as a noninvasive fluorescent marker in living cells and organisms. They enable a wide range of applications where they have functioned as a cell lineage tracer, reporter of gene expression, or as a measure of protein-protein interactions. {ECO:0000305}.

Similarity: Belongs to the GFP family. {ECO:0000269|PubMed:10852900}.
