This is the ubiquitin carboxyl-terminal hydrolase domain found in a variety of proteins, including PAN2, one of the subunits of the poly(A)-specific nuclease (PAN) is a deadenylating enzyme involved in cytoplasmic mRNA turnover (consisting of PAN2 and PAN3), involved in the initial trimming of poly(A) tails [1-3].

RRM, RBD, or RNP domain) is probably diagnostic of an RNA binding protein. RRMs are found in a variety of RNA binding proteins, including various hnRNP proteins, proteins implicated in regulation of alternative splicing, and protein components of snRNPs. The motif also appears in a few single stranded DNA binding proteins. The RRM structure consists of four strands and two helices arranged in an alpha/beta sandwich, with a third helix present during RNA binding in some cases The C-terminal beta strand (4th strand) and final helix are hard to align and have been omitted in the SEED alignment The LA proteins (Swiss:P05455) have an N terminal rrm which is included in the seed. There is a second region towards the C terminus that has some features characteristic of a rrm but does not appear to have the important structural core of a rrm. The LA proteins (Swiss:P05455) are one of the main autoantigens in Systemic lupus erythematosus (SLE), an autoimmune disease.	Domain

This is a pseudokinase (PK) domain found in PAB-dependent poly(A)-specific ribonuclease subunit pan3. PAN3 proteins contain three prominent regions: an unstructured N-terminal region (N-term), a central PK domain, and a highly conserved C-terminal domain (C-term). The PAN3 PK domain has retained its ATP binding capacity, and this function is required for mRNA degradation in vivo. Analysis of Pan3 amino acids sequences show that, despite of retaining the general structural characteristics of protein kinases, the PK domain has substitutions in all the conserved motifs that are critical for kinase activity, such as in the catalytic VAIK and HRD motifs and in the Mg2+ binding DFG motif. However, the PAN3 PK domain has been shown to bind ATP. Furthermore, similar to other kinases, the ATP-binding site is located in the cleft between the N- and C-lobes of the kinase fold, however, the ATP-binding pocket is wider than that of typical kinases [3].
