Function
Granulins have possible cytokine-like activity. They may play a role in inflammation, wound repair, and tissue remodeling.
Granulin-4 promotes proliferation of the epithelial cell line A431 in culture while granulin-3 acts as an antagonist to granulin-4, inhibiting the growth. -
Tissue specificity
In myelogenous leukemic cell lines of promonocytic, promyelocytic, and proerythroid lineage, in fibroblasts, and very strongly in epithelial cell lines. Present in inflammatory cells and bone marrow. Highest levels in kidney. -
Involvement in disease
Defects in GRN are the cause of ubiquitin-positive frontotemporal dementia (UP-FTD) [MIM:607485]; also known as tau-negative frontotemporal dementia linked to chromosome 17. Frontotemporal dementia (FTD) is the second most common cause of dementia in people under the age of 65 years. It is an autosomal dominant neurodegenerative disease. -
Sequence similarities
Belongs to the granulin family. -
Post-translational
modificationsGranulins are disulfide bridged. -

ab208777 Anti-Granulin antibody [EPR15864] was shown to specifically react with Granulin in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266738 (knockout cell lysate ab257235) was used. Wild-type and Granulin knockout samples were subjected to SDS-PAGE. ab208777 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated at room temperature for 2.5 hours at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
