Also known as HGLHugl-2
Summary
LLGL2 (LLGL scribble cell polarity complex component 2, HGNC:6629) is a protein-coding gene on chromosome 17q25.1, encoding LLGL scribble cell polarity complex component 2 (Q6P1M3). Part of a complex with GPSM2/LGN, PRKCI/aPKC and PARD6B/Par-6, which may ensure the correct organization and orientation of bipolar spindles for normal cell division.
The lethal (2) giant larvae protein of Drosophila plays a role in asymmetric cell division, epithelial cell polarity, and cell migration. This human gene encodes a protein similar to lethal (2) giant larvae of Drosophila. In fly, the protein’s ability to localize cell fate determinants is regulated by the atypical protein kinase C (aPKC). In human, this protein interacts with aPKC-containing complexes and is cortically localized in mitotic cells. Alternative splicing results in multiple transcript variants encoding different isoforms.

Function. Part of a complex with GPSM2/LGN, PRKCI/aPKC and PARD6B/Par-6, which may ensure the correct organization and orientation of bipolar spindles for normal cell division. This complex plays roles in the initial phase of the establishment of epithelial cell polarity.
Subunit / interactions. Interacts with GPSM2/LGN, PRKCI/aPKC and PARD6B/Par-6. The complex is enhanced during mitosis. Interacts with DCAF1.
Subcellular location. Cytoplasm.
Post-translational modifications. Phosphorylated at Ser-653 by PRKCI. Phosphorylation is enhanced during cell polarization induced by calcium. Phosphorylation may occur during the cell-cell contact-induced cell polarization and may contribute to the segregation of LLGL2 from the PRKCI/aPKC and PARD6B/Par-6 complex.
Miscellaneous. Overexpression of LLGL2 inhibits the tight junction formation.
Similarity. Belongs to the WD repeat L(2)GL family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 51 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
