Previous GeneCards Identifiers for IL16 Gene
The protein encoded by this gene is a pleiotropic cytokine that functions as a chemoattractant, a modulator of T cell activation, and an inhibitor of HIV replication. The signaling process of this cytokine is mediated by CD4. The product of this gene undergoes proteolytic processing, which is found to yield two functional proteins. The cytokine function is exclusively attributed to the secreted C-terminal peptide, while the N-terminal product may play a role in cell cycle control. Caspase 3 is reported to be involved in the proteolytic processing of this protein. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2010]
GeneCards Summary for IL16 Gene
IL16 (Interleukin 16) is a Protein Coding gene. Diseases associated with IL16 include Whipple Disease and Cd4/Cd8 T-Cell Ratio. Among its related pathways are ERK Signaling and TGF-Beta Pathway. Gene Ontology (GO) annotations related to this gene include cytokine activity. An important paralog of this gene is PDZD2.
UniProtKB/Swiss-Prot Summary for IL16 Gene
Interleukin-16 stimulates a migratory response in CD4+ lymphocytes, monocytes, and eosinophils. Primes CD4+ T-cells for IL-2 and IL-15 responsiveness. Also induces T-lymphocyte expression of interleukin 2 receptor. Ligand for CD4.
Isoform 1 may act as a scaffolding protein that anchors ion channels in the membrane.
Isoform 3 is involved in cell cycle progression in T-cells. Appears to be involved in transcriptional regulation of SKP2 and is probably part of a transcriptional repression complex on the core promoter of the SKP2 gene. May act as a scaffold for GABPB1 (the DNA-binding subunit the GABP transcription factor complex) and HDAC3 thus maintaining transcriptional repression and blocking cell cycle progression in resting T-cells.
