产品介绍background:
SH3MD2 acts as a scaffold protein, contributes to Rac-induced signal transduction such as JNKs (MAPK8 and MAPK9) activation and induces apoptosis. Within a signaling complex, it probably recruits protein kinases such as MAP3K10 or MAP3K11 which are in turn activated leading to the sequential activation of MAP2K4, MAP2K7 and JNKs (MAPK8 and MAPK9). SH3MD2 may be involved in targeting of HIV-1 GAG and GAG-POL polyproteins to the plasma membrane. This gene encodes a protein containing an N-terminus RING-finger, four SH3 domains, and a region implicated in binding of the Rho GTPase Rac. Via the RING-finger, the encoded protein has been shown to function as an ubiquitin-protein ligase involved in protein sorting at the trans-Golgi network. The encoded protein may also act as a scaffold for the c-Jun N-terminal kinase signaling pathway, facilitating the formation of a functional signaling module. There are two named isoforms.
Function:
Acts as a scaffold protein, contributes to Rac-induced signal transduction such as JNKs (MAPK8 and MAPK9) activation and induces apoptosis. Within a signaling complex, it probably recruits protein kinases such as MAP3K10 or MAP3K11 which are in turn activated leading to the sequential activation of MAP2K4, MAP2K7 and JNKs (MAPK8 and MAPK9) (By similarity). May be involved in targeting of HIV-1 GAG and GAG-POL polyproteins to the plasma membrane.
Might act as an E3 ubiquitin-protein ligase, or as part of E3 complex, which accepts ubiquitin from specific E2 ubiquitin-conjugating enzymes such as UBE2D1 or UBE2N and then transfers it to substrates. In the absence of an external substrate, it can catalyze self-ubiquitination. Stimulates ubiquitination of potassium channel KCNJ1, enhancing it's dynamin-dependent and clathrin-independent endocytosis.
Plays an essential role in the targeting of HIV-1 Gag to the plasma membrane, this function is dependent on it's RING domain, and hence it's E3 ligase activity.
Subunit:
Interacts with Rac; in a GTP-dependent manner (By similarity). Interacts with MAP3K10 and MAP3K11. Interacts with MAPK8IP; this interaction leads to the PJAC complex (POSH-JIP or SH3RF1/MAPK8IP apoptotic complex) with a 1:1 ratio. Interacts with SIAH1. Interacts with HERP1. Probably part of a signaling complex that may contain SH3RF1, MAPK8IP, DLK1, MAP2K4, MAP2K7, MAPK8, MAPK9, AKT1 and AKT2.
Subcellular Location:
Cytoplasm, perinuclear region (By similarity). Cell projection, lamellipodium. Cytoplasm. Golgi apparatus, trans-Golgi network. Note=Colocalizes, with AKT2, in lamellipodia (By similarity). Colocalizes, with HERP1, in trans-Golgi network.
Tissue Specificity:
Golgi Apparatus. Lamellipodium. Perinuclear region of cytoplasm.
Post-translational modifications:
Phosphorylated at Ser-304 by AKT1 and AKT2. When phosphorylated, it has reduced ability to bind Rac.
Subject to ubiquitination and proteasomal degradation (By similarity).
Similarity:
Belongs to the SH3RF family.
Contains 1 RING-type zinc finger.
Contains 4 SH3 domains.
Gene ID:
