This family of proteins is found in bacteria and eukaryotes. Proteins in this family are typically between 365 and 621 amino acids in length. There is a conserved LLP sequence motif. KBP is a binding partner for KIF1Balpha that is a regulator of its transport function and thus represents a type of kinesin interacting protein.
