The protein encoded by this gene is a cytokine that belongs to the IL10 cytokine subfamily. This cytokine is found to be preferentially expressed in monocytes. It can bind the IL20 receptor complex and lead to the activation of the signal transducer and activator of transcription 3 (STAT3). A similar cytokine in mouse is reported to up-regulate the expression of IL6 and TNF-alpha and induce apoptosis, which suggests a role of this cytokine in inflammatory responses. Alternatively spliced transcript variants encoding the distinct isoforms have been described. [provided by RefSeq, Jul 2008]
A study in humans identified the IL19 as a candidate mRNA biomarker for the putative identification of vaginal secretions, where it showed no cross-reactivity with saliva but was relatively insensitive, being detected in only 2 out of 5 vaginal samples, making it more suitable for a quantitative (qRT-PCR) assay format [Hanson et al. DOI:10.1016/j.scijus.2012.03.007]. In a subsequent human study, the IL19 was incorporated as a positive control mRNA marker to indicate the presence of vaginal secretions within a multiplex PCR and SNaPshot mini-sequencing system designed for deconvoluting semen donors in body fluid mixtures [Liu et al. DOI:10.1016/j.fsigen.2021.102483].
