Function

May promote proliferation of pancreatic cancer cells by favoring the transition from the S to G2/M phase. In myeloid leukemic cell lines, inhibits cell growth and induces cell differentiation and apoptosis. May play a role in the inhibition of EIF4EBP1 phosphorylation/deactivation. Facilitates cell adhesion, most probably through interaction with cell surface lectins and cadherin.

Biological summary

OLFM4 functions in inhibiting bacterial growth by interfering with bacterial adhesion and survival. It is not part of a larger protein complex but interacts with cell surface proteins to exert its effects. OLFM4 acts in the regulation of cell differentiation and growth playing a significant part in maintaining the stem cell milieu in the intestine.

Mechanical summary

The OLFM4 protein also known as Olfactomedin 4 or GW112 has a molecular weight of around 57 kDa. It is a glycoprotein expressed mainly in human and some non-human primate tissues including the prostate and gastrointestinal tract. OLFM4 is a secreted protein found in various cells including those of the bone marrow and esophagus. It plays a role in innate immunity and is a part of the olfactomedin family which is involved in cell adhesion and migration processes.

Pathway

OLFM4 participates in cellular defense mechanisms primarily against microbial pathogens by involving in the activation of immune response pathways. It is associated with pathways such as the NF-kB signaling and Janus kinase (JAK) pathways. Through these pathways OLFM4 might interact with cytokines and other inflammatory mediators or modulators.

Disease

OLFM4 relates to cancer particularly gastric and colorectal cancer where its expression levels serve as potential biomarkers for disease progression. Additionally it associates with inflammatory bowel diseases impacting the mucosal immune response. In cancer OLFM4's interaction with proteins like MMP isoforms (matrix metalloproteinases) can influence tumor metastasis and invasiveness.

  • Immunocytochemistry/ Immunofluorescence - Anti-OLFM4 antibody (ab85046), expandable thumbnail

    Immunocytochemistry/ Immunofluorescence - Anti-OLFM4 antibody (ab85046)

    ab85046 stained T84 cells. The cells were 4% formaldehyde fixed for 10 minutes at room temperature and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1hour at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab85046 at 5μg/ml) overnight at +4°C. The secondary antibody (pseudo-colored green) was Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) used at a 1/1000 dilution for 1hour at room temperature. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1hour at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43μM for 1hour at room temperature.

  • Western blot - Anti-OLFM4 antibody (ab85046), expandable thumbnail

    Western blot - Anti-OLFM4 antibody (ab85046)

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab85046 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.

  • Immunocytochemistry/ Immunofluorescence - Anti-OLFM4 antibody (ab85046), expandable thumbnail

    Immunocytochemistry/ Immunofluorescence - Anti-OLFM4 antibody (ab85046)

    ab85046 staining OLFM4 in HT29 cells. The cells were fixed with 4% paraformaldehyde (10 min), permeabilized with 0.1% PBS-Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at 4°C with ab85046 at 1µg/ml and ab7291, Mouse monoclonal [DM1A] to alpha Tubulin - Loading Control. Cells were then incubated with ab150081, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 488), pre-adsorbed at 1/1000 dilution (shown in green) and ab150120, Goat polyclonal Secondary Antibody to Mouse IgG - H&L (Alexa Fluor® 594), pre-adsorbed at 1/1000 dilution (shown in pseudocolour red). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown.
