Revision as of 04:27, 26 April 2023
E3 ubiquitin-protein ligase SMURF1 is an enzyme that in humans is encoded by the SMURF1 gene.[8][9] The SMURF1 Gene encodes a protein with a size of 757 amino acids and the molecular mass of this protein is 86114 Da.[10]
Function
Smad ubiquitination regulatory factor 1 (Smurf1) is part of a gene that encodes a ubiquitin ligase and is specific for receptor-regulated SMAD proteins in the bone morphogenetic protein (BMP) pathway.
A similar protein in Xenopus is involved in embryonic pattern formation. Alternative splicing results in multiple transcript variants encoding different isoforms. An additional transcript variant has been identified, but its full length sequence has not been determined.[9]
HIV
The inhibition of HIV-1 replication in HeLa P4/R5 cells can be achieved by siRNA-mediated knockdown of SMURF1.[11]
Cancer
Breast
SMURF1 and SMURF2 have shown to exhibit E3 ligase-dependent and E3 ligase-independent activities in a multitude of different cell types whereby smurfs can act as tumor promoters or tumor suppressors by regulating biological tumorigenesis-related processes. Recent research in breast cancer explains a relationship between SMURF1 and ER alpha (Estrogen receptor alpha) during breast cancer growth. Since ER alpha is expressed in most breast cancers and is attributed to contributing to the progression of estrogen-dependent cancer, it has been supported that the reduction of SMURF1 decreases the proliferation of ER alpha-positive cells in vitro and in vivo.[12] Thus, it is feasible that targeting SMURF1 may become a potential therapy for ER alpha-positive breast cancer.
Gastrointestinal
Smurf1 may the potential to act as an oncogenic factor in other essential organs of the body. For instance, high levels of SMURF1’s are linked to low survival rates of patients who are diagnosed with gastric cancer (GC) and clear cell renal cell carcinoma (ccRCC). Similarly to the suppression of SMURF1 to possibly treat breast cancer, the inhibition of Smurf1 can decrease tumorigenesis in various types of digestive cancer cell models like pancreatic and gastric cancers.[13]
Neurodegenerative Disorders
Continued research shows that SMURF1 can also been linked to various diseases. The downregulation of SMURF1 expression has been observed in neurodegenerative disorders such as Alzheimer's disease and Parkinson’s Disease. Research is showing that SMURF1 plays a role in neuronal necroptosis whereby the up-regulation of Smurf1 was observed in the brain cortex of adult rats who experienced neuroinflammation, and Smurf1 knockdown with siRNA inhibited neuronal necroptosis.[14] This suggests that Smurf1 may promote neuronal necroptosis in neuroinflammatory conditions.
SMURF1 expression was increased in brain tissue samples from Parkinson's disease patients compared to controls, and that this increase was positively correlated with the accumulation of α-synuclein aggregates. Furthermore, the overexpression of SMURF1 in cultured cells led to increased levels of α-synuclein aggregates, while knockdown of SMURF1 reduced α-synuclein aggregation. [15] In the context of neurodegeneration, SMURF1 has been implicated in the regulation of protein quality control mechanisms such as autophagy and the ubiquitin-proteasome system, which are critical for the clearance of misfolded or aggregated proteins that can contribute to disease pathogenesis.
While the exact mechanisms by which SMURF1 contributes to neurodegenerative disorders are still not fully understood, there is growing evidence, research studies may suggest that SMURF1 may be a potential target for therapeutic intervention in protein aggregation and improving cellular proteostasis in neurodegenerative diseases. [16]
Post Translational Modifications
Under the influence of NDFIP1, it undergoes auto-ubiquitination. The SMURF1 protein is modified by the SCF(FBXL15) complex at two lysine residues, Lys-381 and Lys-383, which leads to its degradation by the proteasome. Whereby, Lys-383 is the primary site of ubiquitination.[17]
Interactions
Smurfs are composed of several distinct domains that include an N-terminal C2 domain, two to three WW domains containing tryptophan residues, and an HECT domain. The C2 domain plays a crucial role in mediating the interaction of Smurfs with intracellular membranes. On the other hand, the WW domains of Smurfs are typically involved in protein-protein interactions, allowing them to interact with various target proteins.[18] SMURF1 https://linkinghub.elsevier.com/retrieve/pii/S0197458014006435has been shown to interact with:
- ARHGEF9[19]
- PLEKHO1[20]
- SMURF2[21]
- TRAF4[22]
- Interacts with FBXL15 (via HECT domain)[22]
- SMAD7[22]
- TGFBR1[22]
