[X] SPCC1494.09c tfb6 re- included in unknowns After conversation with Rob Nash at SGD, I am going to revert TFB6 to "unknown" process (and probably remove TFIIIB)

An excerpt:

This 2016 paper does not show it as a bona fida complex member. https://www.ncbi.nlm.nih.gov/pubmed/27381459 Other oddity is that the abstract reports a high similarity to a human protein, but this does not exist. This seems to be fungal specific (which is very rare for general TFs).

I will revert the PomBase annotation to "unknown" process

Actually, I see what you mean. Although TFB6 is a component of the complex, it may not function in the context of transcription if it is ssl2 for use in other contexts.

Hmm, not sure. I'm going to ask for advice on how others would annotate this. To me, it seems odd to say something is core TFIID, and then not have a transcription process based on this observation. But as you say the exact role in transcription is not established (I definitely wouldn't make a "NOT" annotation to show a lack of involvement based on the in vitro assay, because this does not rule out a role in transcription.....

On 17/08/2018 18:55, Rob Nash wrote:

Hi Val,

Thanks for clarifying and providing a possible paper to use in annotation. This subunit was identified much later than the rest of those for TFIID, and the gene/protein has not been well studied. I took a look at the paper you suggested, and in this paper they show no impact on in vitro transcriptional initiation or preinitiation complex (PIC) assembly. Add back experiments did not impact transcriptional initiation either. So I think this why we did not annotate the suggested process, and I am uncomfortable adding an IC followed by a NOT annotation.

The only observation of note in this paper is that in the presence of phosphorylated Tfb6p, the Ssl2p helicase subunit, tends to dissociate from TFIID and forms a heterodimer with Tfb6p. However, if Ssl2p is already assembled into a complete preinitation complex than Tfb6p appears unable to dissociate the helicase. So the only term I have been able come up would be this one:

GO:0034367 protein-containing complex remodeling The acquisition, loss, or modification of macromolecules within a complex, resulting in the alteration of an existing complex.

and the evidence is not strong. In the paper they basically study TFIID subunit composition in the absence and presence of TFB6, and then follow this up by add back experiments where some Ssl2p is now lost from TFIID and appears in complex with Tfb6p.

So I wonder if you have any thoughts on whether this would be an accurate annotation based on the evidence and of use to you. I am on the fence about adding this one.

ValWood commented 6 years ago

[x] Spp41 can only have "regulation of gene expression'

Edith: "Yes, from that paper, I would agree that it is just suppression of a cold phenotype. I've removed that annotation and replaced it with GO:0010629 (Neg. regulation of gene expression, has_input PRP4|PRP3) since there's increase in PRP4 and PRP3 expression in a spp41 mutant."

So, this one will not be specific enough for our slim (could be txn, translation, processing, maturation). This one will come back into "unknowns"

[x] ess1 name added, but I think this will probably stay as colour10. It's still unknown physiological role. name description, DUF Eight-Six-Six;

authors speculate oxidative phosphorylation, but really its more closely aligned with MAPK pathway and response to oxidative stress.

That's great. It's still unknown as I expected since its phenotypes not GO.

yup, and just H2O2 sensitivity at that.

An unknown protein spbc14C8.13 ber1 has been renamed as srr1

It was annotated SRR1 family protein, implicated in microtubule stabilization (yeast), and heme biosynthesis (mouse)

is now published in Fission yeast Srr1 and Skb1 promote isochromosome formation at the centromere PMID: 37237082

I don't know if we will get a GO process from the publication, so it could still be classed as "poorly characterized". This is a nice illustration of GO annotations in other species made from phenotypes which we would not make the corresponding inferred annotations. I think the only evidence for the yeast annotation was benomyl resistance. On its own this isn't enough to infer a GO process. We can only make annotations from phenotypes if we are confident the phenotype is specific for the process, OR if there are multiple lines of evidence.

Maybe its protein maturation since "The pattern of synthetic lethal interactions obtained with the ber1Δ mutant suggests that Ber1 may function in N-terminal protein acetylation."PMID: 18064466 A synthetic lethal screen approach suggested that Ber1 is implicated in a number of cellular functions, and most prominently in kinetochore function. Synthetic lethal screen analyses revealed that Rpn4, Ard1, Nat1 and Ber1 share a wide set of genetic interactions (Fig. 2). Our data therefore suggest that Ber1 may function in protein N-terminus acetylation and/or proteasome biogenesis. Since proteasome subunits are heavily N-acetylated (Csank et al. 2002), the role of Ber1 in proteasome assembly might be a secondary consequence of its role in protein modification. Thus, we suggest that Ber1 might be an accessory factor for the N-terminal acetyltransferase. We would however like to point out that with the currently available data this is only a working hypothesis.
