Secreted Ly-6/uPAR-related protein 1 is a protein that in humans is encoded by the SLURP1 gene. [5] [6] [7] It exerts anti-inflammatory effects, acts as a tumor suppressor, and antagonizes nicotinic receptors. [8]

Contents

Function

The protein encoded by this gene is a member of the Ly6/uPAR family but lacks a GPI-anchoring signal sequence. It is secreted into the blood [6] and is also sometimes found in semen when extracted into the female zygote which binds to the α7-acetylcholine receptor. [8] It is shown to act as an endogenous tumor suppressor by reducing cell migration and invasion by mediating its own anti-tumor effect and by antagonizing the pro-malignant effects of nicotine. [8]

Mutations in this gene have been associated with Mal de Meleda, a rare autosomal recessive skin disorder characterized by an inflammatory palmoplantar hyperkeratosis. This is the consequence of a loss of SLURP1 which leads to a dysfunctional epithelial differentiation [9] and an increased secretion of the inflammatory cytokines TNFα, IL1, IL-6, and IL-8. [10] [11]

This gene maps to the same chromosomal region as several members of the Ly6/uPAR family of glycoprotein receptors. [7]

Meleda disease (MDM) or "mal de Meleda", also called Mljet disease, keratosis palmoplantaris and transgradiens of Siemens, is an extremely rare autosomal recessive congenital skin disorder in which dry, thick patches of skin develop on the soles of the hands and feet, a condition known as palmoplantar hyperkeratosis. Meleda Disease is a skin condition which usually can be identified not long after birth. This is a genetic condition but it is very rare. The hands and feet usually are the first to show signs of the disease but the disease can advance to other parts of the body. Signs of the disease include thickening of the skin, on hands and soles of feet, which can turn red in color. There currently is no cure and treatment is limited, but Acitretin can be used in severe cases.

Fibrillin-1 is a protein that in humans is encoded by the FBN1 gene, located on chromosome 15. It is a large, extracellular matrix glycoprotein that serves as a structural component of 10-12 nm calcium-binding microfibrils. These microfibrils provide force bearing structural support in elastic and nonelastic connective tissue throughout the body. Mutations altering the protein can result in a variety of phenotypic effects differing widely in their severity, including fetal death, developmental problems, Marfan syndrome or in some cases Weill-Marchesani syndrome.

For chromosome 20, R-spondin 4 is a protein in humans that is encoded by the RSPO4 gene. This gene encodes a member of the R-spondin family of proteins that share a common domain organization consisting of a signal peptide, cysteine-rich/furin-like domain, thrombospondin domain and a C-terminal basic region. The encoded protein may be involved in activation of Wnt/beta-catenin signaling pathways. Mutations in this gene are associated with anonychia congenita. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Sep 2009].

Ly6 also known as lymphocyte antigen 6 or urokinase-type plasminogen activator receptor (uPAR) is family of proteins that share a common structure but differ in their tissue expression patterns and function. Ly6 are cysteine-rich proteins that form disulfide bridges and contain a LU domain. These proteins are GPI-anchored to the cell membrane or are secreted. A total of 35 human and 61 mouse Ly6 family members have been identified. Depending on which tissues they are expressed in, LY6 family members have different roles. They are expressed in various types of tissues and their expression dependent on the stage of cell differentiation. For example, they are involved in cell proliferation, cell migration, cell–cell interactions, immune cell maturation, macrophage activation, and cytokine production. Their overexpression or dysregulation, for example due to point mutations, is associated with tumorogenesis and autoimmune diseases. This family was discovered in the 1970s, and these proteins are still used as markers of distinct stage of leukocyte differentiation.
