This is a family of short ubiquitin-like proteins, that is like neither type-1 or type-2. It is a ubiquitin-fold modifier 1 (Ufm1) that is synthesised in a precursor form of 85 amino-acid residues. In humans the enzyme for Ufm1 is Uba5 and the conjugating enzyme is Ufc1. Prior to activation by Uba5 the extra two amino acids at the C-terminal region of the human pro-Ufm1 protein are removed to expose Gly whose residue is necessary for conjugation to target molecule(s). The mature Ufm1 is conjugated to yet unidentified endogenous proteins,[1]. While Ubiquitin and many Ubls possess the conserved C-terminal di-glycine that is adenylated by each specific E1 or E1-like enzyme, respectively, in an ATP-dependent manner, Ufm1(1-83) possesses a single glycine at its C-terminus, which is followed by a Ser-Cys dipeptide in the precursor form of Ufm1. The C-terminally processed Ufm1(1-83) is specifically activated by Uba5, an E1-like enzyme, and then transferred to its cognate Ufc1, an E2-like enzyme [2].

This entry represents the fifth winged helix-turn-helix (wHTH) domain found in the UFL1 protein. Winged helix-turn-helix domains are structural motifs commonly involved in protein-protein interactions and DNA binding. In the context of UFL1, this domain is part of a complex protein involved in the UFM1 conjugation system and protein UFMylation.

This domain is found C-terminal in human E3 UFM1-protein ligase 1 (UFL1) and similar eukaryotic sequences. UFL1 mediates ufmylation, the covalent attachment of the ubiquitin-like modifier UFM1 to lysine residues on target proteins, which plays a key role in reticulophagy induced in response to endoplasmic reticulum stress [1]. UFL1 is a component of the UFM1 ribosome E3 ligase (UREL) complex which is involved in the release and recycling of stalled or terminated ribosomes from the ER membrane [2]. This domain is predicted to adopt globular structure consisting of an array of alpha-helices.

This domain occurs in proteins that have been annotated as Fibronectin/fibrinogen binding protein by similarity. This annotation comes from Swiss:O34693 where the N-terminal region is involved in this activity [1]. It is an RNA binding domain of the NFACT (NEMF, FbpA, Caliban, and Tae2) proteins. This NFACT-R family is found in two eukaryotic gene contexts: fused to the NFACT-N and NFACT-C domains in the NFACT protein involved in the ribosomal quality control pathway which contributes to CAT-tailing and as a standalone domain [2]. Additionally this domain contains a conserved motif D/E-X-W/Y-X-H that may be functionally important.

This entry represents a domain that structurally resembles the ubiquitin conjugating enzyme domain Pfam:PF00179 and the RWD domain Pfam:PF05773. This domain is somewhat smaller and apparently lacks the conserved cysteine that is used for ubiquitin conjugation. This domain is commonly found in the LTN1 family that comprises E3 ubiquitin-protein ligases involved in the ribosome quality control complex (RQC). The RQC is a ribosome-associated complex that targets incompletely synthesized nascent chains for proteasomal degradation. Members of the LTN1 family are responsible for ubiquitinating stalled nascent chains on the 60S ribosomal subunit, a process facilitated by the recruitment of NEMF in some species. This ubiquitination signals the recruitment of cellular machinery such as VCP/p97, TER94/VCP, or CDC48, depending on the organism, to extract and degrade the incomplete translation products. The LTN1 family plays a crucial role in maintaining protein synthesis fidelity by ensuring the removal of defective ribosomal products, thereby preventing the accumulation of potentially toxic protein fragments within the cell.
