Tissue specificity: Predominantly highly expressed in liver sinusoidal endothelial cells and in lymph node. Found in placental endothelium but not in macrophages. Expressed in type II alveolar cells and lung endothelial cells. {ECO:0000269|PubMed:11226297, ECO:0000269|PubMed:11257134, ECO:0000269|PubMed:15496474}.
Domain: The tandem repeat domain, also called neck domain, mediates oligomerization.
Polymorphism: The number of repeats in the tandem repeat domain is shown to vary between 3 and 9 per allele thus contributing to a further variability in addition to alternative splicing. The shown 7 repeat- containing form has been shown to be the most frequent one (53.9%) in a study with 350 Caucasian individuals.
Miscellaneous: In vitro, is a receptor for HIV-1 and transmits HIV-1 to permissive T-cells.
Miscellaneous: [Isoform 2]: May be due to intron retention. {ECO:0000305}.
Miscellaneous: [Isoform 6]: May be due to intron retention. {ECO:0000305}.
Miscellaneous: [Isoform 8]: Non-canonical intron-exon splice junction. {ECO:0000305}.
