UniProt functional annotation for P25090

UniProt code: P25090.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: Low affinity receptor for N-formyl-methionyl peptides, which are powerful neutrophil chemotactic factors (PubMed:1374236). Binding of FMLP to the receptor causes activation of neutrophils (PubMed:1374236). This response is mediated via a G-protein that activates a phosphatidylinositol-calcium second messenger system (PubMed:1374236). The activation of LXA4R could result in an anti- inflammatory outcome counteracting the actions of proinflammatory signals such as LTB4 (leukotriene B4) (PubMed:9547339). Receptor for the chemokine-like protein FAM19A5, mediating FAM19A5-stimulated macrophage chemotaxis and the inhibitory effect on TNFSF11/RANKL- induced osteoclast differentiation (By similarity). {ECO:0000250|UniProtKB:O88536, ECO:0000269|PubMed:1374236, ECO:0000269|PubMed:9547339}.
 
Subunit: Interacts with Amyloid-beta protein 42, product of APP; the interaction takes place at the cell surface and the complex is then rapidly internalized. {ECO:0000269|PubMed:11689470}.
Subunit: (Microbial infection) Interacts with Staphylococcus aureus protein SSL13; this interaction leads to the activation of neutrophils. {ECO:0000269|PubMed:30098280}.
Subcellular location: Cell membrane {ECO:0000269|PubMed:11689470}; Multi-pass membrane protein. Note=Associates with Amyloid-beta protein 42, product of APP, at the cell surface and the complex is then rapidly internalized. {ECO:0000269|PubMed:11689470}.
Tissue specificity: Expressed abundantly in the lung and neutrophils. Also found in the spleen and testis. {ECO:0000269|PubMed:9151906}.
Similarity: Belongs to the G-protein coupled receptor 1 family. {ECO:0000255|PROSITE-ProRule:PRU00521}.
