HOMOLOGY

Homologene

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane
	intracellular
	intracellular,cytoplasm,cytosolic,vesicle
text	presynaptic membrane and presynaptic active zone of both asymmetrical(excitatory) and symmetrical (inhibitory) synapses

basic FUNCTION	playing a role in neuronal plasticity and the proteolytic action
	may be crucial for adaptative synaptic functions, such as those required to establish and/or maintain higher cognitive functions
	mosaic serine proteases having several domains in the proenzyme fragment, which modulate proteolytic function
	multidomain protein that serves as a brain-specific serine protease
	preferentially affects social behaviors, and modulates the functions of hippocampal neurons
	mosaic serine protease secreted by neuronal cells, that is believed to be important for cognitive function
	plays a significant role in cognitive function and the development of the brain, since the loss of motopsin function causes severe mental retardation
	is activity-dependently secreted from neuronal cells, is captured around the synaptic cleft
	serine protease neurotrypsin, cleaves the heparan sulfate proteoglycan agrin
	AGRN and neurotrypsin (PRSS12) are associated with muscle mass, strength and plasma C-terminal agrin fragment concentration

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

neurotrypsin/agrin system implicated in the regulation of adaptive reorganizations of the synaptic circuitry in the context of cognitive functions, such as learning and memory

INTERACTION

DNA

RNA

small molecule

protein	ITM2A is a motopsin-interacting protein
	secreted motopsin interacts likely with endothelial cells in the developing brain
	cleaves a proteoglycan, agrin
	SEZ6 bound to the proline-rich/kringle domain of motopsin, and interaction of motopsin and SEZ6 modulates the neuronal cell morphology
