Descriptions

NTRK1 is a high-affinity nerve growth factor receptor and its ligand is nerve growth factor (NGF), which is involved in the survival, differentiation, development, and maturation of the central and peripheral nervous systems, particularly the sensory and sympathetic neurons. Studies have shown that deletion of the second Ig-like domain of NTRK1 results in spontaneous activation, so the second Ig-like domain is an autoinhibitory domain required to prevent spontaneous activation by receptor dimerization.

7 GO annotations of cellular component

Name Definition
axon The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
glutamatergic synapse A synapse that uses glutamate as a neurotransmitter.
Golgi membrane The lipid bilayer surrounding any of the compartments of the Golgi apparatus.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
postsynaptic membrane A specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters cross the synaptic cleft and transmit the signal to the postsynaptic membrane.
receptor complex Any protein complex that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

32 GO annotations of biological process

Name Definition
axon extension involved in regeneration Long distance growth of a single axon process involved in regeneration of the neuron.
cellular response to nerve growth factor stimulus A process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nerve growth factor stimulus.
cellular response to retinoic acid Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a retinoic acid stimulus.
circadian rhythm Any biological process in an organism that recurs with a regularity of approximately 24 hours.
cochlea development The progression of the cochlea over time from its formation to the mature structure. The cochlea is the snail-shaped portion of the inner ear that is responsible for the detection of sound.
heart development The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.
lens fiber cell differentiation The process in which a relatively unspecialized cell acquires specialized features of a lens fiber cell, any of the elongated, tightly packed cells that make up the bulk of the mature lens in the camera-type eye. The cytoplasm of a lens fiber cell is devoid of most intracellular organelles including the cell nucleus, and contains primarily crystallins, a group of water-soluble proteins expressed in vary large quantities.
mechanoreceptor differentiation The process in which a relatively unspecialized cell acquires specialized features of a mechanoreceptor, a cell specialized to transduce mechanical stimuli and relay that information centrally in the nervous system.
myelination in peripheral nervous system The process in which neuronal axons and dendrites become coated with a segmented lipid-rich sheath (myelin) to enable faster and more energetically efficient conduction of electrical impulses. The sheath is formed by the cell membranes of Schwann cells in the peripheral nervous system. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier.
