PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	very long terminal extension with a high proline content preceding the motor domain comprising one consensus ATP binding site and two putative actin-binding sites
	a neck containing two IQ calmodulin or calmodulin-like chain binding domains and
	a tail containing two myosin IV-like,and two C terminal talin-like (FERM) (EPB41,ezrin,radixin,moesin) domains, involved in the linkage of cytoplasmic proteins to the membrane
	a putative SH3 domain

HOMOLOGY

FAMILY

myosin family

CATEGORY

motor/contractile

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm,cytoskeleton,intermed filament
text	linked to the plasma membrane

basic FUNCTION	involved in structure and function of auditory and vestibular hair cells
	playing a necessary role for actin organization in the hair cells of the cochlea
	may be having a role in secretory granule movement and/or hormone secretion
	motor protein, necessary for the development of hair cell stereocilia, which are actin-filled projections on the apical surface and the site of mechanotransduction of sound
	may be involved in cytoplasmic organelle movement, including secretory granules in pituitary cells and pituitary adenomas
	traffics and delivers critical molecules required for stereocilia development and thus is essential for building the mechanosensory hair bundle

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

sensory transduction/hearing

a component	MYO15A, DFNB31, and EPS8 are integral components of the stereocilia tip complex, where EPS8 is a central actin-regulatory element for elongation of the stereocilia actin core
	MYO15A-EPS8 complex transports BAIAP2L2 to stereocilia tips, and Ca2+ entry through open channels at row 2 tips retains BAIAP2L2 there

INTERACTION

DNA

RNA

small molecule

protein

BAIAP2L2 localization to stereocilia tips is dependent on the motor protein MYO15A and its cargo EPS8
