background:
Involved in vesicular transport in the osteoclast (By similarity). May have a role in sialyl-lex-mediated transduction of apoptotic signals.
Tissue specificity: Expressed in placenta, liver, prostate, thymus, spleen, ovary, colon, colon carcinoma and peripheral blood lymphocytes (PBL). Weakly expressed in brain, lung, kidney, and testis. No expression in heart, skeletal muscle, pancreas and small intestine. Predominantly expressed in the breast carcinoma cell line MCF-7.
Involvement in disease:Defects in PLEKHM1 are the cause of osteopetrosis autosomal recessive type 6 (OPTB6); also known as autosomal recessive osteopetrosis intermediate form. Osteopetrosis is a rare genetic disease characterized by abnormally dense bone, due to defective resorption of immature bone. The disorder occurs in two forms: a severe autosomal recessive form occurring in utero, infancy, or childhood, and a benign autosomal dominant form occurring in adolescence or adulthood. Autosomal recessive osteopetrosis is usually associated with normal or elevated amount of non-functional osteoclasts.
Function:
Involved in vesicular transport in the osteoclast (Bysimilarity). May have a role in sialyl-lex-mediated transduction ofapoptotic signals.
Subunit:
In colon carcinoma and breast carcinoma cells, itinteracts with sialyl-lex-positive protein.
Subcellular Location:
Cytoplasm (Potential).
Tissue Specificity:
Expressed in placenta, liver, prostate,thymus, spleen, ovary, colon, colon carcinoma and peripheral bloodlymphocytes (PBL). Weakly expressed in brain, lung, kidney, andtestis. No expression in heart, skeletal muscle, pancreas and smallintestine. Predominantly expressed in the breast carcinoma cellline MCF-7.
