Background: Neuroligin 4Y/NLGN4Y

Neuroligin 4 (NLGN4, NL4 or NL4X) is a type I transmembrane molecule in the type-B carboxyesterase/lipase family of proteins. Neuroligins are postsynaptically expressed on neurons and initiate excitatory presynapse maturation through binding to select isoforms of b-neurexin (1). Human NLGN4 maps to the X-chromosome and shares 98% aa identity with the Y-chromosome-encoded NLGN4Y (2). Mature human NLGN4Y consists of a 633 aa extracellular domain (ECD), a 21 aa transmembrane domain and a 119 aa cytoplasmic tail. It is expressed in the frontal cortex, temporal cortex, occipital cortex, hippocampus, cerebellum, and spinal cord (3, 4). The ECD possesses a nonfunctional esterase homology domain through which neuroligins, except for NLGN2, interact with neurexins (5). Alternative splicing of NLGN4Y generates additional isoforms with variable N-terminal deletions and/or insertions and truncations within the ECD. NLGNs 3, 4, and 4Y bind to the intracellular adaptor protein Syntrophin-g2 (6). Mutations of NLGN4 but not NLGN4Y are associated with rare cases of autism and Asperger or Tourette syndromes (4, 7-12).
