Kelch_1

PFAM accession number:	PF01344
Interpro abstract (IPR006652):	Kelch is a 50-residue motif, named after the Drosophila mutant in which it was first identified [ (PUBMED:8453663) ]. This sequence motif represents one beta-sheet blade, and several of these repeats can associate to form a beta-propeller. For instance, the motif appears 6 times in Drosophila egg-chamber regulatory protein (also known as ring canal kelch protein), creating a 6-bladed beta-propeller. The motif is also found in mouse protein MIPP [ (PUBMED:8453663) ] and in a number of poxviruses. In addition, kelch repeats have been recognised in alpha- and beta-scruin [ (PUBMED:7593276) (PUBMED:7822422) ], and in galactose oxidase from the fungus Dactylium dendroides [ (PUBMED:8126718) (PUBMED:2002850) ]. The structure of galactose oxidase reveals that the repeated sequence corresponds to a 4-stranded anti-parallel beta-sheet motif that forms the repeat unit in a super-barrel structural fold [ (PUBMED:8182749) ]. The known functions of kelch-containing proteins are diverse: scruin is an actin cross-linking protein; galactose oxidase catalyses the oxidation of the hydroxyl group at the C6 position in D-galactose; and kelch may have a cytoskeletal function, as it is localised to the actin-rich ring canals that connect the 15 nurse cells to the developing oocyte in Drosophila [ (PUBMED:7593276) ]. Nevertheless, based on the location of the kelch pattern in the catalytic unit in galactose oxidase, functionally important residues have been predicted in glyoxal oxidase [ (PUBMED:8126718) ]. This entry represents a type of kelch sequence motif that comprises one beta-sheet blade.
