The ion channels activated by glutamate are typically divided into two classes. Those that are sensitive to N-methyl-D-aspartate (NMDA) are designated NMDA receptors (NMDAR) while those activated by alpha-amino-3-hydroxy-5-methyl-4-isoxalone propionic acid (AMPA) are known as AMPA receptors (AMPAR). The AMPAR are comprised of 4 distinct subunits (GluR1-4) and they play key roles in virtually all excitatory neurotransmission in the brain. The GluR1 subunit is widely expressed throughout the nervous system. GluR1 is also potentiated by phosphorylation at Ser845. In addition, phosphorylation of this site has been linked to synaptic plasticity as well and learning and memory.

DEAF1 down-regulates transcription of those genes by binding to sequence with multiple copies of TTC[CG]G present in their own promoter and that of the HNRPA2B1 gene. DEAF1 binds to the retinoic acid response element (RARE) AGGGTTCACCGAAAGTTCA. DEAF1 activates the proenkephalin gene independently of promoter binding, probably through protein-protein interaction. When secreted, behaves as an inhibitor of cell proliferation, by arresting cells in the G0 or G1 phase.

SAP30BP expressed as a fusion polypeptide with a fluorescent protein in the nucleus of HeLa cells. SAP30BP induces cell death. The interaction of SAP30BP with SAP30 in its conserved domain implies that this protein family, as the products of immediate-early genes, comprise functional molecules involved in the transcriptional regulation of cells, which might be related to the inhibition of some cell survival genes. SAP30BP may also be involved in the regulation of beta-2-microglobulin genes.

Inhibits NF-κ-B by complexing with and trapping it in the cytoplasm. However, the unphosphorylated form resynthesized after cell stimulation is able to bind NF-κ-B allowing its transport to the nucleus and protecting it to further IKBA-dependent inactivation. Association with inhibitor kappa B-interacting NKIRAS1 and NKIRAS2 prevent its phosphorylation rendering it more resistant to degradation, explaining its slower degradation.

Vinculin is a cytoskeletal protein that plays an important role in the regulation of focal adhesions and embryonic development. Three structural vinculin domains include an amino-terminal head, a short flexible proline-rich region and a carboxy-terminal tail. Expression of vinculin were shown to be affected by the level of actin expression. Vinculin deficiencies are associated with a decrease in cell adhesion and an increase in cell motility, suggesting a possible role in metastatic growth. Defects in VCL are the cause of cardiomyopathy dilated type 1W (CMD1W).

PARP2 contains a catalytic domain and is capable of catalyzing a poly (ADP-ribosyl)ation reaction. This protein has a catalytic domain which is homologous to that of poly (ADP-ribosyl) transferase, but lacks an N-terminal DNA binding domain which activates the C-terminal catalytic domain of poly (ADP-ribosyl) transferase. The basic residues within the N-terminal region of this protein may bear potential DNA-binding properties, and may be involved in the nuclear and/or nucleolar targeting of protein.

The B- and T-lymphocyte attenuator (BTLA) protein is a member of the immunoglobulin superfamily containing a single immunoglobulin (Ig) domain. Like other coihibitory receptors such as CTLA-4 and PD-1, BTLA functions as a receptor that relays inhibitory signals to suppress the immune response, and can inhibit LPS-induced endotoxic shock by suppressing TLR4 signaling in innate immune cells (1,2). Polymorphisms in this gene have also been associated with an increased risk of rheumatoid arthritis.

Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization.
