Involved in neural development, regulating the establishment of proper connectivity within the nervous system. Acts as a homophilic and heterophilic synaptic cell adhesion molecule that drives synapse assembly. Promotes bi-directional trans-synaptic signaling with Ten-a to organize neuromuscular synapses. Functions in olfactory synaptic partner matching by promoting homophilic cell adhesion between pre-synaptic olfactory receptor neurons (ORN) axons and post-synaptic projection neurons (PN) dendrites partner in the developing antennal lobe to form stable connections. Also required for peripheral axon growth cone guidance and target recognition of motor neurons. Homodimer. Heterodimer with Ten-a. Interacts with Ten-a; the interaction occurs at the neuromuscular junction. Interacts with alpha-Spec and cher. Localizes at neuromuscular junction. Localizes in neuron cell bodies. Colocalizes with alpha-Spec at the membranous subsynaptic reticulum (SSR). Expressed in muscles and motor neurons (at protein level). Expressed in the central nervous system and heart. Expressed in the developing antennal lobe. Expressed in subset of matching olfactory receptor neurons (ORN) and projection neurons (PN) in select glomeruli between 12 to 48 hours after puparium formation (apf) (at protein level). Expressed in odd-numbered blastoderm parasegments, the central nervous system, muscle attachment points and tracheal precursor cells. Expressed in the ventral nerve cord, the cardiac mesoderm and epidermis at late embryonic stages. Expressed in all imaginal disks. Phosphorylated. Phosphorylation occurs at tyrosine residues. Proteolytically cleaved. Shows peripheral motor neuron axon guidance defects. The name odz (odd Oz) reflects the odd pair rule nature of the gene and Oz reflects the prominent expression of the gene in the brain, heart and neurons, corresponding to the three gifts that the Wizard of Oz bestowed. Belongs to the tenascin family. Teneurin subfamily. Truncated N-terminus.
