RT by cells of the innate immune system.";
RL J. Immunol. 169:4822-4830(2002).
CC -!- FUNCTION: May play a role in the regulation of immune cell function.
CC Cytokine that imparts cellular protection against viral infection in a
CC species-specific manner. Activates the interferon-stimulated response
CC element signaling pathway. It is able to directly modulate cytokine
CC release from monocytes and dendritic cells. Binds heparin.
CC {ECO:0000269|PubMed:11514542, ECO:0000269|PubMed:12391192}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Expressed in keratinocytes, monocytes and in
CC resting dendritic cells. {ECO:0000269|PubMed:11514542,
CC ECO:0000269|PubMed:12391192}.
CC -!- INDUCTION: By viral infection, upon exposure to double-stranded RNA, or
CC upon treatment with either interferon-gamma or interferon-beta.
CC {ECO:0000269|PubMed:11514542}.
CC -!- SIMILARITY: Belongs to the alpha/beta interferon family. {ECO:0000305}.
