Acts as a guanine nucleotide exchange factor (GEF) for RAN GTPase (By similarity). May play an essential role in hemostasis and in maintaining microtubule dynamics with respect to both platelet shape and function (By similarity). May act as an adapter protein to couple membrane receptors to intracellular signaling pathways. Enhances dihydrotestosterone-induced transactivation activity of AR, as well as dexamethasone-induced transactivation activity of NR3C1, but does not affect estrogen-induced transactivation. In contrast to RANBP9, does not interact with Sos and does not activate the Ras pathway.

May act as an adapter protein to couple membrane receptors to intracellular signaling pathways. May be involved in signaling of ITGB2/LFA-1 and other integrins. Enhances HGF-MET signaling by recruiting Sos and activating the Ras pathway. Enhances dihydrotestosterone-induced transactivation activity of AR, as well as dexamethasone-induced transactivation activity of NR3C1, but not affect estrogen-induced transactivation. Stabilizes TP73 isoform Alpha, probably by inhibiting its ubiquitination, and increases its proapoptotic activity. Inhibits the kinase activity of DYRK1A and DYRK1B. Inhibits FMR1 binding to RNA.

May be involved in JAK/STAT signaling. Isoform D is required for the proper arrangement of niche cells and is autonomously required for proper niche cell size, isoform C negatively regulates the adhesive properties of the niche. The germline stem cell (GSC) niche in ovaries is made up of two somatic cell types: 8-9 cells in a single-filed array make up the terminal filament (TF), and a tight cluster of 5 or 6 cap cells (CpC). Regulating the size and adhesive properties of the CpCs is an important component of the mechanism that controls their capacity to support stem cells, isoform C and isoform D are important factors in mediating this regulation. In contrast, isoform C acts as a positive regulator of cell adhesion in follicle cell epithelium.

This family includes SPRY domain in Ran binding protein (RBP or RanBPM) 9 and 10, and similar proteins. RanBP9 (also known as RanBPM), a binding partner of Ran, is a small Ras-like GTPase that exerts multiple functions via interactions with various proteins. RanBP9 and RanBP10 also act as androgen receptor (AR) coactivators. Both consist of the N-terminal proline- and glutamine-rich regions, the SPRY domain, and LisH-CTLH and CRA motifs. SPRY domain of RanBPM forms a complex with CD39, a prototypic member of the NTPDase family, thus down-regulating activity substantially. RanBP10 enhances the transcriptional activity of AR in a ligand-dependent manner and exhibits a protein expression pattern different from RanBPM in various cell lines. RanBP10 is highly expressed in AR-positive prostate cancer LNCaP cells, while RanBPM is abundant in WI-38 and MCF-7 cells. Length = 153
>gnl|CDD|240465 cd12885, SPRY_RanBP_like, SPRY domain in Ran binding proteins, SSH4, HECT E3 and SPRYD3
This family includes SPRY domains found in Ran binding proteins (RBP or RanBPM) 9 and 10, SSH4 (suppressor of SHR3 null mutation protein 4), SPRY domain-containing protein 3 (SPRYD3) as well as HECT, a C-terminal catalytic domain of a subclass of ubiquitin-protein ligase (E3). RanBP9 and RanBP10 act as androgen receptor (AR) coactivators. Both consist of the N-terminal proline- and glutamine-rich regions, the SPRY domain, and LisH-CTLH and CRA motifs. The SPRY domain in SSH4 may be involved in cargo recognition, either directly or by combination with other adaptors, possibly leading to a higher selectivity. SPRYD3 is highly expressed in most tissues in humans, possibly involved in important cellular processes. HECT E3 mediates the direct transfer of ubiquitin from E2 to substrate. Length = 132
>gnl|CDD|240488 cd12908, SPRYD3, SPRY domain-containing protein 3
This family contains SPRY domain-containing protein 3 (SPRYD3). In humans, it is highly expressed in most tissues, including brain, kidney, heart, intestine, skeletal muscle, and testis. It also has cross-species conservation, suggesting that it is likely to carry out important cellular processes. Length = 171
Distant homologues are domains in butyrophilin/marenostrin/pyrin []. Ca2+-release from the sarcoplasmic or endoplasmic reticulum, the intracellular Ca2+ store, is mediated by the ryanodine receptor (RyR) and/or the inositol trisphosphate receptor (IP3R).; GO: 0005515 protein binding; PDB: 2V24_A 3EK9_A 2AFJ_A 2IWG_E 3EMW_A 2WL1_A 3TOJ_B 2VOK_A 2VOL_B 2FNJ_A ....
