Function
Secreted protein that acts as a key regulator of lysosomal function and as a growth factor involved in inflammation, wound healing and cell proliferation (PubMed:28541286, PubMed:28073925, PubMed:18378771, PubMed:28453791, PubMed:12526812). Regulates protein trafficking to lysosomes and, also the activity of lysosomal enzymes (PubMed:28453791, PubMed:28541286). Facilitates also the acidification of lysosomes, causing degradation of mature CTSD by CTSB (PubMed:28073925). In addition, functions as wound-related growth factor that acts directly on dermal fibroblasts and endothelial cells to promote division, migration and the formation of capillary-like tubule structures (By similarity). Also promotes epithelial cell proliferation by blocking TNF-mediated neutrophil activation preventing release of oxidants and proteases (PubMed:12526812). Moreover, modulates inflammation in neurons by preserving neurons survival, axonal outgrowth and neuronal integrity (PubMed:18378771). UniProt

Subunit Structure
Progranulin is secreted as a homodimer (PubMed:23364791). Interacts with SLPI; interaction protects progranulin from proteolysis (PubMed:12526812). Interacts (via region corresponding to granulin-7 peptide) with CTSD; stabilizes CTSD and increases its proteolytic activity (PubMed:28453791). Interacts (via region corresponding to granulin-7 peptide) with SORT1; this interaction mediates endocytosis and lysosome delivery of progranulin; interaction occurs at the neuronal cell surface in a stressed nervous system (PubMed:21092856). Interacts with PSAP; facilitates lysosomal delivery of progranulin from the extracellular space and the biosynthetic pathway (PubMed:26370502). Forms a complex with PSAP and M6PR; PSAP bridges the binding between progranulin and M6PR (PubMed:26370502). Forms a complex with PSAP and SORT1; progranulin bridges the interaction between PSAP and SORT1; facilitates lysosomal targeting of PSAP via SORT1; interaction enhances PSAP uptake in primary cortical neurons (PubMed:28541286). Interacts (via regions corresponding to granulin-2 and granulin-7 peptides) with GBA; this interaction prevents aggregation of GBA-SCARB2 complex via interaction with HSPA1A upon stress (PubMed:27789271). Interacts (via region corresponding to granulin-7 peptide) with HSPA1A; mediates recruitment of HSPA1A to GBA and prevents GBA aggregation in response to stress (PubMed:27789271). UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
