Modulates exocytosis of dense-core granules and secretion of hormones in the pancreas and the pituitary. Interacts with vesicles containing negatively charged phospholipids in a Ca(2+)-independent manner.

Determined the solution structure of human synaptotagmin-like protein 4 (Slp4). Through modification of cysteine residues, found Slp4 binding of two zinc atoms is required for correct folding. PMID: 28906046
Granuphilin makes granules immobile and fusion-reluctant beneath the plasma membrane. Those granuphilin-positive, docked granules release a portion of granuphilin upon fusion, and fuse at a frequency and time course similar to those of granuphilin-negative undocked granules. Granuphilin forms a 180-nm cluster at the site of each docked granule, along with granuphilin-interacting Rab27a and Munc18-1 clusters. PMID: 27032672
GLUT5 required an interaction cascade of Rab11, Myo5B, Slp4a, Munc18-2, and Vamp7 with Stx3. PMID: 26553929
Phosphatidylinositol 4,5-bisphosphate binds to the concave surface of granuphilin-C2A domain. The key residues involved in the binding were validated by mutation analysis. PMID: 25595293
the mechanisms of granuphilin plasma membrane targeting and release PMID: 24184645
Recruitment of STXBP1 by the Rab27A effector SYTL4 promotes Weibel-Palade body exocytosis. PMID: 24700782
Slp4 and Rab8 are expressed and interact in human platelets, and might be involved in dense granule release. PMID: 23140275
in insulin-producing cells adequate levels of mir-9 are mandatory for maintaining appropriate Granuphilin levels and optimal secretory capacity PMID: 16831872
Synaptotagmin-like protein 4 (Slp4)/granuphilin-a contains an N-terminal Slp homology domain (SHD) (PMID: 11327731). The SHD of Slp4 specifically and directly binds the GTP-bound form of Rab3A, Rab8, and Rab27A. PMID: 11773082
