Protein: L2GL1_HUMAN

Lethal(2) giant larvae protein homolog 1

FUNCTION: Cortical cytoskeleton protein found in a complex involved in maintaining cell polarity and epithelial integrity. Involved in the regulation of mitotic spindle orientation, proliferation, differentiation and tissue organization of neuroepithelial cells. more...

SUBUNIT: Associated with nonmuscle myosin II heavy chain. Interacts with PRKCI/aPKC, PARD6B/Par-6 and PARD6A. Interacts with STX4A (By similarity).

SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. Note=Localized to the lateral membrane during the polarization and formation cell- cell contacts.

TISSUE SPECIFICITY: Expressed in brain, kidney, and muscle but is barely seen in heart and placenta. Down-regulated or lost in all cell lines and in most of the tumor samples analyzed. Loss was associated with advanced stage of the disease.

PTM: Phosphorylated upon DNA damage, probably by ATM or ATR (By similarity). Phosphorylated at least at Ser-663 by PRKCI. MISCELLANEOUS: Down-regulation of LLGL1 is associated with the progression of colorectal cancer and melanoma. Located within the Smith-Magenis syndrome region on chromosome 17; deleted in patients with this syndrome. MISCELLANEOUS: Expression increases cell adhesion and decreases cell migration. Substitutes for Drosophila l(2)gl tumor suppressor function in vivo.

SIMILARITY: Belongs to the WD repeat L(2)GL family.

SIMILARITY: Contains 14 WD repeats.

SEQUENCE CAUTION: Sequence=BAA19516.1; Type=Frameshift; Positions=205, 216, 737, 740, 794, 799, 866, 872, 881, 945, 968, 1024;

GENE SYNONYMS: DLG4 HUGL HUGL1.
