Neurexin-3-alpha is a protein that in humans is encoded by the NRXN3 gene.^[3]^[4]^[5]

Neurexins are a family of proteins that function in the vertebrate nervous system as cell adhesion molecules and receptors. They are encoded by several unlinked genes of which two, NRXN1 and NRXN3, are among the largest known human genes. Three of the genes (NRXN1-3) utilize two alternate promoters and include numerous alternatively spliced exons to generate thousands of distinct mRNA transcripts and protein isoforms. The majority of transcripts are produced from the upstream promoter and encode alpha-neurexin isoforms; a much smaller number of transcripts are produced from the downstream promoter and encode beta-neurexin isoforms. The alpha-neurexins contain epidermal growth factor-like (EGF-like) sequences and laminin G domains, and have been shown to interact with neurexophilins. The beta-neurexins lack EGF-like sequences and contain fewer laminin G domains than alpha-neurexins.^[5] NRXN3 is thought to be involved in synaptic plasticity, and polymorphisms in NRXN3 have been linked to genetic predisposition towards a number of conditions such as alcohol or drug addiction,^[6]^[7]^[8] or obesity.^[9]

Laminins are a family of glycoproteins of the extracellular matrix of all animals. They are major constituents of the basement membrane, namely the basal lamina. Laminins are vital to biological activity, influencing cell differentiation, migration, and adhesion.

Neurexins (NRXN) are a family of presynaptic cell adhesion proteins that have roles in connecting neurons at the synapse. They are located mostly on the presynaptic membrane and contain a single transmembrane domain. The extracellular domain interacts with proteins in the synaptic cleft, most notably neuroligin, while the intracellular cytoplasmic portion interacts with proteins associated with exocytosis. Neurexin and neuroligin "shake hands," resulting in the connection between the two neurons and the production of a synapse. Neurexins mediate signaling across the synapse, and influence the properties of neural networks by synapse specificity. Neurexins were discovered as receptors for α-latrotoxin, a vertebrate-specific toxin in black widow spider venom that binds to presynaptic receptors and induces massive neurotransmitter release. In humans, alterations in genes encoding neurexins are implicated in autism and other cognitive diseases, such as Tourette syndrome and schizophrenia.

Latrophilin 1 is a protein that in humans is encoded by the ADGRL1 gene. It is a member of the adhesion-GPCR family of receptors. Family members are characterized by an extended extracellular region with a variable number of protein domains coupled to a TM7 domain via a domain known as the GPCR-Autoproteolysis INducing (GAIN) domain.

CD79b molecule, immunoglobulin-associated beta, also known as CD79B, is a human gene.

Neuroligin (NLGN), a type I membrane protein, is a cell adhesion protein on the postsynaptic membrane that mediates the formation and maintenance of synapses between neurons. Neuroligins act as ligands for β-neurexins, which are cell adhesion proteins located presynaptically. Neuroligin and β-neurexin "shake hands", resulting in the connection between two neurons and the production of a synapse. Neuroligins also affect the properties of neural networks by specifying synaptic functions, and they mediate signalling by recruiting and stabilizing key synaptic components. Neuroligins interact with other postsynaptic proteins to localize neurotransmitter receptors and channels in the postsynaptic density as the cell matures. Additionally, neuroligins are expressed in human peripheral tissues and have been found to play a role in angiogenesis. In humans, alterations in genes encoding neuroligins are implicated in autism and other cognitive disorders. Antibodies in a mother from previous male pregnancies against neuroligin 4 from the Y chromosome increase the probability of homosexuality in male offspring.

Contactin-associated protein-like 4 is a protein that in humans is encoded by the CNTNAP4 gene.

Synapsin II is the collective name for synapsin IIa and synapsin IIb, two nearly identical phosphoproteins in the synapsin family that in humans are encoded by the SYN2 gene. Synapsins associate as endogenous substrates to the surface of synaptic vesicles and act as key modulators in neurotransmitter release across the presynaptic membrane of axonal neurons in the nervous system.

SNED1 is an extracellular matrix (ECM) protein expressed at low levels in a wide range of tissues. The gene encoding SNED1 is located in the human chromosome 2 at locus q37.3. The corresponding mRNA isolated from the spleen and is 6834bp in length, and the corresponding protein is 1413 amino-acid long. The mouse ortholog of SNED1 was cloned in 2004 from the embryonic kidney by Leimester et al. SNED1 present domains characteristic of ECM proteins, including an amino-terminal NIDO domain, several calcium binding EGF-like domains (EGF_CA), a Sushi domain also known as complement control protein (CCP) domain, and three type III fibronectin (FN3) domains in the carboxy-terminal region.
