UniProt annotation for HECAM_HUMAN » Hepatocyte cell adhesion molecule
FUNCTION: Involved in regulating cell motility and cell-matrix interactions. May inhibit cell growth through suppression of cell proliferation.

SUBUNIT: Homodimer. Dimer formation occurs predominantly through cis interactions on the cell surface. Part of a complex containing MLC1, TRPV4, AQP4 and ATP1B1.

INDUCTION: Down-regulated in 20 out of 23 of hepatocellular carcinoma (HCC) samples and is undetectable in 5 HCC cell lines tested.

DOMAIN: The cytoplasmic domain plays an important role in regulation of cell-matrix adhesion and cell motility.

DISEASE: Leukoencephalopathy, megalencephalic, with subcortical cysts, 2A (MLC2A) OMIM: A neurodegenerative disorder characterized by infantile-onset macrocephaly and later onset of motor deterioration, with ataxia and spasticity, seizures, and cognitive decline of variable severity. The brain appears swollen on magnetic resonance imaging with white-matter abnormalities and subcortical cysts, in all stages of the disease. mutations affecting the gene represented in this entry.

DISEASE: Leukoencephalopathy, megalencephalic, with subcortical cysts, 2B (MLC2B) OMIM: A neurodegenerative disorder characterized by infantile-onset of macrocephaly and mildly delayed motor development associated with white-matter abnormalities on brain magnetic resonance imaging. The phenotype is milder that MLC2A, with better preserved cerebellar white matter and no subcortical cysts outside the temporal region. On follow-up, patients show normal or almost normal motor function. Some patients have normal intelligence, whereas others have a significant cognitive deficiency. Note=The disease is caused by mutations affecting the gene represented in this entry.
