Ankyrin repeat and FYVE domain-containing protein 1 is a

protein Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metab ...

gene In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protei ...

BTB/POZ domain The BTB/POZ domain (BTB for BR-C, ttk and bab or POZ for Pox virus and Zinc finger) is a structural domain found in proteins across the domain Eukarya. Given its prevalence in eukaryotes and its absence in Archaea and bacteria, it likely arose aft ...

N-terminus The N-terminus (also known as the amino-terminus, NH2-terminus, N-terminal end or amine-terminus) is the start of a protein or polypeptide, referring to the free amine group (-NH2) located at the end of a polypeptide. Within a peptide, the amin ...

ankyrin repeat The ankyrin repeat is a 33-residue motif in proteins consisting of two alpha helices separated by loops, first discovered in signaling proteins in yeast Cdc10 and '' Drosophila'' Notch. Domains consisting of ankyrin tandem repeats mediate ...
