Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Lysophosphatidylserine (LPS) lipase that mediates the hydrolysis of lysophosphatidylserine, a class of signaling lipids that regulates immunological and neurological processes (PubMed:25290914, PubMed:30237167, PubMed:30420694, PubMed:30720278, PubMed:30643283).

Represents a major lysophosphatidylserine lipase in the brain, thereby playing a key role in the central nervous system (By similarity).

Also able to hydrolyze oxidized phosphatidylserine; oxidized phosphatidylserine is produced in response to severe inflammatory stress and constitutes a proapoptotic 'eat me' signal (PubMed:30643283).

Also has monoacylglycerol (MAG) lipase activity: hydrolyzes 2-arachidonoylglycerol (2-AG), thereby acting as a regulator of endocannabinoid signaling pathways (PubMed:22969151, PubMed:24027063).

Has a strong preference for very-long-chain lipid substrates; substrate specificity is likely due to improved catalysis and not improved substrate binding (PubMed:30237167).

Caution

A family suffering from Polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and cataract (PHARC) was initially clinically diagnosed with Usher syndrome type 3 (PubMed:22938382). Reexamination of one affected member of this family revealed ataxia but not polyneuropathy, demonstrating the phenotypic heterogeneity in PHARC and the need for careful neurological assessments to distinguish this disease from other neuropathic disorders (PubMed:22938382).1 Publication
