The protein encoded by this gene is a member of the LAR protein-tyrosine phosphatase-interacting protein (liprin) family. Liprins interact with members of LAR family of transmembrane protein tyrosine phosphatases, which are known to be important for axon guidance and mammary gland development. It has been proposed that liprins are multivalent proteins that form complex structures and act as scaffolds for the recruitment and anchoring of LAR family of tyrosine phosphatases. This protein was found to interact with S100A4, a calcium-binding protein related to tumor invasiveness and metastasis. In vitro experiment demonstrated that the interaction inhibited the phosphorylation of this protein by protein kinase C and protein kinase CK2. Alternatively spliced transcript variants encoding distinct isoforms have been reported.[7]
Interactions
PPFIBP1 has been shown to interact with liprin-alpha-1.[5]
gollark: Pretty much everything we actually produce is in the "not entirely necessary but nice to have" box.
gollark: There is lots of stuff which nobody really *needs* - you can live without it, society could work without it (if we had set stuff up that way) - but it's not very nice to not have it. Like computers, or modern medicine, or non-bare-minimum food and housing.
gollark: Food is, broadly speaking, necessary to live. But while I could probably *survive* on cheaper, less resource-intensive-to-produce food than I do, or less food by caloric content and stuff, I like to have more/better food than is strictly necessary. Same with water - I won't die of dehydration on some small amount per day, but on the whole I'll be worse off if I don't have as much to drink as I want, or enough water for showering and washing stuff.
gollark: I'm typing.
gollark: You totally did.
