Background
Neural
cell adhesion molecule 1 (NCAM-1), also known as CD56, is a multifunctional
member of the Ig superfamily. It belongs to a family of membrane-bound
glycoproteins that are involved in Ca
++ independent cell matrix and
homophilic or heterophilic cell-cell interactions. There are three main forms
of human NCAM-1 that arise by alternate splicing. These are designated
NCAM-120/NCAM-1 761 amino acid (aa), NCAM-140 (848 aa), and NCAM-180 (1120 aa). NCAM-120 is
GPI-linked, while NCAM-140 and NCAM-180 are type I transmembrane glycoproteins
(1-3). Additional alternate splicing adds considerable diversity to all three
forms, and extracellular proteolytic processing is possible for NCAM-180 (4, 5).
Human NCAM-1 is synthesized as a 761 aa preproprecursor, containing a signal
sequence, a large GPI-linked extracellular domain (ECD), and a short C-terminal
prosegment (1). The mature ECD contains five C-2 type Ig-like domains and two
fibronectin type III domains. The mature human ECD shares 93% and 95% aa
sequence identity with the mouse and rat NCAM-1 ECD, respectively. NCAM-1
appears to be highly sialylated. The polysialyation of NCAM-1 reduces its
adhesive property and increases its neurite outgrowth promoting features (6).
NCAM-1 in the adult brain shows a decline of sialylation relative to earlier
developmental periods. In regions that retain a high degree of neuronal
plasticity, however, the adult brain continues to express
polysialylated-NCAM-1, suggesting sialylation of NCAM-1 is involved in
regenerative processes and synaptic plasticity (7-10). NCAM can function as a receptor for GDNF
family of ligands. GDNF stimulates Schwann cell migration and neurite outgrowth
in hippocampal and cortical neurons through binding to NCAM-1 and activation of
Fyn, independently of RET (11). NCAM-1 also interacts with Ig IIIC isoform of
the FGFR1 and plays an important role in developmental events as well as tumor
progression (12). It promotes ovarian
cancer progression through FGF R1 interaction and stimulates dissemination of
tumor to organs of peritoneal cavity (13).
NCAM-1 is preferentially expressed in NK cells and a subset of T lymphocytes that mediate MHC-unrestricted cell-mediated cytotoxicity (14). High expression of CD56/NCAM-1 differentiates
NK cells as having an activated phenotype. CD56(+high) NK cells mediate
heightened effector functions (proliferation, IFN-gamma and IL-10 but not IL-13
production) in response to IL-12 (15). NCAM-1 functions as pathogen recognition
receptor during an innate immune response (16).
CD56
+ T cells can inhibit HIV infection of macrophages (17). Due to
expression on immune cells NCAM-1 has great implications on tumor progression,
infection, and disease development.
