This data was developed using ab307091, the same antibody clone in a different buffer formulation. Blocking and diluting buffer and concentration : Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS. Lysates at 20 µg per lane. Performed under reducing conditions. False colour image of Western blot : Anti-CARM1 antibody EPR26711-36 ab307091 staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody 6C5 loading control staining at 1/20000 dilution, shown in red. In Western blot, ab307091 was shown to bind specifically to CARM1. A band was observed at 63 kDa in wild-type HEK293T cell lysates with no signal observed at this size in CARM1 knockout cell line (knockout cell lysate). To generate this image, wild-type and CARM1 knockout HEK293T cell lysates were analyzed. First, samples were run on an SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in in Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

Supplementary information

CARM1 also known as PRMT4 is a protein with a mass of approximately 65 kDa. It belongs to the protein arginine methyltransferase (PRMT) family of enzymes. CARM1 modifies histones by methylating arginine residues which plays a role in regulating transcription. This protein expresses widely across diverse tissues but shows higher levels in the lung thymus and spleen. These expression patterns suggest its broad function in modulating gene expression within specialized tissues.
Biological function summary

CARM1 serves as an important regulator of transcriptional activation. It can act independently or as part of a multiprotein complex to enhance transcription factor activity including steroid hormone receptors. In addition to histones CARM1 targets non-histone proteins like p300/CBP which affects their coactivator functions. It has a significant impact on gene expression by altering chromatin structure and accessibility thereby influencing cellular processes like differentiation and proliferation.

Pathways

One can find CARM1 involved in pathways controlling gene expression and cell cycle regulation. The protein is particularly important in the estrogen receptor signaling pathway where it interacts with the estrogen receptor alpha (ERα) and modulates transcriptional activation of estrogen-responsive genes. It also plays a role in the p53 signaling pathway by enhancing p53-mediated transcriptional activation linking CARM1 to cell cycle arrest and apoptosis. Both pathways highlight its importance in cellular growth and homeostasis.

Abnormalities in CARM1 function connect to specific cancers including breast and prostate cancer. Its deregulation leads to altered methylation patterns that can drive cancer progression and metastasis. CARM1 influences the expression and activity of proteins such as cyclin D1 which affects cell cycle progression and tumor growth. Understanding the involvement of CARM1 in these disorders opens potential therapeutic avenues for targeting its aberrant pathways in cancer treatment.

Target data

Methylates (mono- and asymmetric dimethylation) the guanidino nitrogens of arginyl residues in several proteins involved in DNA packaging, transcription regulation, pre-mRNA splicing, and mRNA stability (PubMed : 12237300, PubMed : 16497732, PubMed : 19405910). Recruited to promoters upon gene activation together with histone acetyltransferases from EP300/P300 and p160 families, methylates histone H3 at 'Arg-17' (H3R17me), forming mainly asymmetric dimethylarginine (H3R17me2a), leading to activation of transcription via chromatin remodeling (PubMed : 12237300, PubMed : 16497732, PubMed : 19405910). During nuclear hormone receptor activation and TCF7L2/TCF4 activation, acts synergically with EP300/P300 and either one of the p160 histone acetyltransferases NCOA1/SRC1, NCOA2/GRIP1 and NCOA3/ACTR or CTNNB1/beta-catenin to activate transcription (By similarity). During myogenic transcriptional activation, acts together with NCOA3/ACTR as a coactivator for MEF2C (By similarity). During monocyte inflammatory stimulation, acts together with EP300/P300 as a coactivator for NF-kappa-B (By similarity). Acts as a coactivator for PPARG, promotes adipocyte differentiation and the accumulation of brown fat tissue (By similarity). Plays a role in the regulation of pre-mRNA alternative splicing by methylation of splicing factors (By similarity). Also seems to be involved in p53/TP53 transcriptional activation (By similarity). Methylates EP300/P300, both at 'Arg-2142', which may loosen its interaction with NCOA2/GRIP1, and at 'Arg-580' and 'Arg-604' in the KIX domain, which impairs its interaction with CREB and inhibits CREB-dependent transcriptional activation (PubMed : 15731352). Also methylates arginine residues in RNA-binding proteins PABPC1, ELAVL1 and ELAV4, which may affect their mRNA-stabilizing properties and the half-life of their target mRNAs (By similarity). Acts as a transcriptional coactivator of ACACA/acetyl-CoA carboxylase by enriching H3R17 methylation at its promoter, thereby positively regulating fatty acid synthesis (By similarity). Independently of its methyltransferase activity, involved in replication fork progression : promotes PARP1 recruitment to replication forks, leading to poly-ADP-ribosylation of chromatin at replication forks and reduced fork speed (PubMed : 33412112).
