General description

Monoclonal Anti-LIS1 (mouse IgG1 isotype) is derived from the LIS1-338 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from a BALB/c mouse immunized with a recombinant human LIS1 protein. The LIS1 protein (46 kDa) contains seven WD (tryptophan-aspartic acid) repeats, a motif shared by at least 140 known proteins.
The gene PAFAH1B1 (platelet activating factor acetylhydrolase 1b regulatory subunit 1) encodes a protein named LIS1 (lissencephaly-1) that forms the α subunit of the intracellular Ib isoform of platelet-activating factor acteylhydrolase (PAFAH). The gene is mapped to human chromosome 17p13.3.

Specificity

By immunoblotting, the antibody prefers the phosphorylated form of the LIS1 molecule (46 kDa).

Immunogen

recombinant human LIS1 protein.

Application

Monoclonal Anti-LIS1 antibody produced in mouse has been used in protein pulldown assay and immunofluorescence.

Biochem/physiol Actions

LIS1 is involved in cell regulation, including the β subunits of G-proteins (Gβ). This protein motif is likely to mediate protein-protein interactions. LIS1 is a protein that is highly conserved during evolution; bovine, mouse, and chicken proteins exceed 99% similarity.
The heterotrimeric enzyme, platelet-activating factor acteylhydrolase (PAFAH), catalyzes the cleavage of acetyl group at the SN-2 position of platelet-activating factor. The α subunit encoded by the gene PAFAH1B1 (platelet activating factor acetylhydrolase 1b regulatory subunit 1) interacts with tubulin and affects microtubule dynamics. Mutations in this gene have been linked to Miller–Dieker lissencephaly, a human brain malformation characterized by a smooth cerebral surface and a disordered organization of the cortical layers resulting from a defect in neuronal migration.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
