Summary: Enables ribonucleoprotein complex binding activity. Involved in several processes, including negative regulation of protein import into nucleus during spindle assembly checkpoint; nucleocytoplasmic transport; and post-transcriptional tethering of RNA polymerase II gene DNA at nuclear periphery. Located in nuclear envelope; nucleoplasm; and spindle pole body. Part of nuclear pore nuclear basket. Used to study lung cancer. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder. Orthologous to human TPR (translocated promoter region, nuclear basket protein).

Mlp1p and Mlp2p are necessary components of the nuclear basket and they embed the nuclear pore complex within a dynamic protein network
Title: The nuclear basket proteins Mlp1p and Mlp2p are part of a dynamic interactome including Esc1p and the proteasome.
Mlps link mRNA transcription and export
Title: Perinuclear Mlp proteins downregulate gene expression in response to a defect in mRNA export.
Mlp2p links the SPB to the peripheral Mlp assembly, and this linkage is required for efficient incorporation of components into the SPB.
Title: The nuclear pore complex-associated protein, Mlp2p, binds to the yeast spindle pole body and promotes its efficient assembly.
Mlps play important roles in regulating Ulp1 and subsequently affect sumoylation stasis, growth, and DNA repair.
Title: Mlp-dependent anchorage and stabilization of a desumoylating enzyme is required to prevent clonal lethality.
