What's a GeneRIF?

PTIP associated protein 1, PA1, is an independent prognostic factor for lymphnode negative breast cancer.
Title: PTIP associated protein 1, PA1, is an independent prognostic factor for lymphnode negative breast cancer.
PA1 expression was observed in both nucleus (mainly)and cytoplasm from breast cancer tissue samples. PA1 nuclear expression was correlated with postmenopausal, smaller tumor size, negative Ki67, positive AR and positive ERbeta. PA1 nuclear positive cases seemed to have a longer survival than negative ones for RFS. For those patients without lymphnode metastasis PA1 was found to be an independent prognostic factor for RFS.
Title: PTIP associated protein 1, PA1, is an independent prognostic factor for lymphnode negative breast cancer.
PA1 is a new competitive decelerator of GR transactivation and can act at more than one molecularly defined step in a manner that depends upon the specific gene
Title: PA1 protein, a new competitive decelerator acting at more than one step to impede glucocorticoid receptor-mediated transactivation.
subset of PTIP.PA1 complex is recruited to DNA damage sites via the RNF8-dependent pathway and is required for cell survival in response to DNA damage.
Title: Accumulation of Pax2 transactivation domain interaction protein (PTIP) at sites of DNA breaks via RNF8-dependent pathway is required for cell survival after DNA damage.
GAS is a new transcription cofactor
Title: GAS, a new glutamate-rich protein, interacts differentially with SRCs and is involved in oestrogen receptor function.
PA1 (C16orf53) binds PTIP directly and requires PTIP for interaction with the MLL3- and MLL4-containing histone H3 K4 methyltransferase complex.
Title: PTIP associates with MLL3- and MLL4-containing histone H3 lysine 4 methyltransferase complex.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
